1003 background_color_even => "lightblue", #cell background color for even rows
1006 # do other stuff with $pdf
1012 For a complete working example or initial script look into distribution`s 'examples' folder.
1017 This class is a utility for use with the PDF::API2 module from CPAN.
1018 It can be used to display text data in a table layout within a PDF.
1019 The text data must be in a 2D array (such as returned by a DBI statement handle fetchall_arrayref() call).
1020 The PDF::Table will automatically add as many new pages as necessary to display all of the data.
1021 Various layout properties, such as font, font size, and cell padding and background color can be specified for each column and/or for even/odd rows.
1022 Also a (non)repeated header row with different layout properties can be specified.
1024 See the L</METHODS> section for complete documentation of every parameter.
1030 my $pdf_table = new PDF::Table;
1036 Creates a new instance of the class. (to be improved)
1040 There are no parameters.
1044 Reference to the new instance
1050 my ($final_page, $number_of_pages, $final_y) = table($pdf, $page, $data, %settings)
1056 Generates a multi-row, multi-column table into an existing PDF document based on provided data set and settings.
1060 $pdf - a PDF::API2 instance representing the document being created
1061 $page - a PDF::API2::Page instance representing the current page of the document
1062 $data - an ARRAY reference to a 2D data structure that will be used to build the table
1063 %settings - HASH with geometry and formatting parameters.
1065 For full %settings description see section L</Table settings> below.
1067 This method will add more pages to the pdf instance as required based on the formatting options and the amount of data.
1071 The return value is a 3 items list where
1073 $final_page - The first item is a PDF::API2::Page instance that the table ends on
1074 $number_of_pages - The second item is the count of pages that the table spans on
1075 $final_y - The third item is the Y coordinate of the table bottom so that additional content can be added in the same document.

1246 =item B<new_page_func> - CODE reference to a function that returns a PDF::API2::Page instance.
1248 If used the parameter 'new_page_func' must be a function reference which when executed will create a new page and will return the object back to the module.
1249 For example you can use it to put Page Title, Page Frame, Page Numbers and other staff that you need.
1250 Also if you need some different type of paper size and orientation than the default A4-Portrait for example B2-Landscape you can use this function ref to set it up for you. For more info about creating pages refer to PDF::API2 PAGE METHODS Section.
1251 Don't forget that your function must return a page object created with PDF::API2 page() method.
1253 new_page_func => $code_ref
1255 =item B<header_props> - HASH reference to specific settings for the Header row of the table. See section L</Header Row Properties> below

1265 cell_props => $cel_props
1267 =item B<cell_render_hook> - CODE reference to a function called with the current cell coordinates. If used the parameter 'cell_render_hook' must be a function reference. It is most useful for creating a url link inside of a cell. The following example adds a link in the first column of each non-header row:
1269 cell_render_hook => sub {
1270 my ($page, $first_row, $row, $col, $x, $y, $w, $h) = @_;
1272 # Do nothing except for first column (and not a header row)
1273 return unless ($col == 0);
1274 return if ($first_row);
1277 my $value = $list_of_vals[$row-1];
1278 my $url = "https://${hostname}/app/${value}";
1280 my $annot = $page->annotation();
1281 $annot->url( $url, -rect => [$x, $y, $x+$w, $y+$h] );
1286 =head4 Header Row Properties
1288 If the 'header_props' parameter is used, it should be a hashref. Passing an empty HASH will trigger a header row initialised with Default values.
1289 There is no 'data' variable for the content, because the module asumes that first table row will become the header row. It will copy this row and put it on every new page if 'repeat' param is set.
1293 =item B<font> - instance of PDF::API2::Resource::Font defining the fontf to be used in the header row
1295 B<Value:> can be any PDF::API2::Resource::* type of font
1296 B<Default:> 'font' of the table. See table parameter 'font' for more details.
1298 =item B<font_size> - Font size of the header row
1300 B<Value:> can be any positive number
1301 B<Default:> 'font_size' of the table + 2
1303 =item B<font_color> - Font color of the header row
1305 B<Value:> Color specifier as 'name' or 'HEX'
1306 B<Default:> '#000066'
1308 =item B<font_underline> - Font underline of the header row
1310 B<Value:> 'auto', integer of distance, or arrayref of distance & thickness (more than one pair will provide mlultiple underlines. Negative distance gives strike-through.
1313 =item B<bg_color> - Background color of the header row
1315 B<Value:> Color specifier as 'name' or 'HEX'
1318 =item B<repeat> - Flag showing if header row should be repeated on every new page
1320 B<Value:> 0,1 1-Yes/True, 0-No/False
1323 =item B<justify> - Alignment of text in the header row.
1325 B<Value:> One of 'left', 'right', 'center'
1326 B<Default:> Same as column alignment (or 'left' if undefined)
1330 font => $pdf->corefont("Helvetica", -encoding => "utf8"),
1332 font_color => '#004444',
1333 bg_color => 'yellow',
1340 =head4 Column Properties
1342 If the 'column_props' parameter is used, it should be an arrayref of hashrefs,
1343 with one hashref for each column of the table. The columns are counted from left to right so the hash reference at $col_props[0] will hold properties for the first column from left to right.
1344 If you DO NOT want to give properties for a column but to give for another just insert and empty hash reference into the array for the column that you want to skip. This will cause the counting to proceed as expected and the properties to be applyed at the right columns.
1346 Each hashref can contain any of the keys shown below:
1350 =item B<min_w> - Minimum width of this column. Auto calculation will try its best to honour this param but aplying it is NOT guaranteed.
1352 B<Value:> can be any whole number satisfying 0 < min_w < w
1353 B<Default:> Auto calculated
1355 =item B<max_w> - Maximum width of this column. Auto calculation will try its best to honour this param but aplying it is NOT guaranteed.
1357 B<Value:> can be any whole number satisfying 0 < max_w < w
1358 B<Default:> Auto calculated
1360 =item B<font> - instance of PDF::API2::Resource::Font defining the fontf to be used in this column
1362 B<Value:> can be any PDF::API2::Resource::* type of font
1363 B<Default:> 'font' of the table. See table parameter 'font' for more details.
1365 =item B<font_size> - Font size of this column
1367 B<Value:> can be any positive number
1368 B<Default:> 'font_size' of the table.
1370 =item B<font_color> - Font color of this column
1372 B<Value:> Color specifier as 'name' or 'HEX'
1373 B<Default:> 'font_color' of the table.
1375 =item B<font_underline> - Font underline of this cell
1377 B<Value:> 'auto', integer of distance, or arrayref of distance & thickness (more than one pair will provide mlultiple underlines. Negative distance gives strike-through.
1380 =item B<background_color> - Background color of this column
1382 B<Value:> Color specifier as 'name' or 'HEX'
1385 =item B<justify> - Alignment of text in this column
1387 B<Value:> One of 'left', 'right', 'center'
1393 {},# This is an empty hash so the next one will hold the properties for the second column from left to right.
1395 min_w => 100, # Minimum column width of 100.
1396 max_w => 150, # Maximum column width of 150 .
1397 justify => 'right', # Right text alignment
1398 font => $pdf->corefont("Helvetica", -encoding => "latin1"),
1400 font_color=> 'blue',
1401 background_color => '#FFFF00',
1408 NOTE: If 'min_w' and/or 'max_w' parameter is used in 'col_props', have in mind that it may be overridden by the calculated minimum/maximum cell witdh so that table can be created.
1409 When this happens a warning will be issued with some advises what can be done.
1410 In cases of a conflict between column formatting and odd/even row formatting, 'col_props' will override odd/even.
1412 =head4 Cell Properties
1414 If the 'cell_props' parameter is used, it should be an arrayref with arrays of hashrefs
1415 (of the same dimension as the data array) with one hashref for each cell of the table.
1417 Each hashref can contain any of the keys shown below:
1421 =item B<font> - instance of PDF::API2::Resource::Font defining the fontf to be used in this cell
1423 B<Value:> can be any PDF::API2::Resource::* type of font
1424 B<Default:> 'font' of the table. See table parameter 'font' for more details.
1426 =item B<font_size> - Font size of this cell
1428 B<Value:> can be any positive number
1429 B<Default:> 'font_size' of the table.
1431 =item B<font_color> - Font color of this cell
1433 B<Value:> Color specifier as 'name' or 'HEX'

1436 =item B<font_underline> - Font underline of this cell
1438 B<Value:> 'auto', integer of distance, or arrayref of distance & thickness (more than one pair will provide mlultiple underlines. Negative distance gives strike-through.
1441 =item B<background_color> - Background color of this cell
1443 B<Value:> Color specifier as 'name' or 'HEX'
1446 =item B<justify> - Alignment of text in this cell
1448 B<Value:> One of 'left', 'right', 'center'
1454 [ #This array is for the first row. If header_props is defined it will overwrite these settings.
1456 background_color => '#AAAA00',
1457 font_color => 'yellow',
1458 font_underline => [ 2, 2 ],
1465 background_color => '#CCCC00',
1466 font_color => 'blue',
1469 background_color => '#BBBB00',
1470 font_color => 'red',
1479 my $cell_props = [];
1480 $cell_props->[1][0] = {
1482 background_color => '#CCCC00',
1483 font_color => 'blue',
1488 NOTE: In case of a conflict between column, odd/even and cell formatting, cell formatting will overwrite the other two.
1489 In case of a conflict between header row and cell formatting, header formatting will override cell.
1493 my ($width_of_last_line, $ypos_of_last_line, $left_over_text) = text_block( $txt, $data, %settings)
1499 Utility method to create a block of text. The block may contain multiple paragraphs.
1500 It is mainly used internaly but you can use it from outside for placing formatted text anywhere on the sheet.
1502 NOTE: This method will NOT add more pages to the pdf instance if the space is not enough to place the string inside the block.
1503 Leftover text will be returned and has to be handled by the caller - i.e. add a new page and a new block with the leftover.
1507 $txt - a PDF::API2::Page::Text instance representing the text tool
1508 $data - a string that will be placed inside the block
1509 %settings - HASH with geometry and formatting parameters.
1513 The return value is a 3 items list where
1515 $width_of_last_line - Width of last line in the block
1516 $final_y - The Y coordinate of the block bottom so that additional content can be added after it
1517 $left_over_text - Text that was did not fit in the provided box geometry.
