653 my $pdf = new PDF::API2(-file => "table_of_lorem.pdf");
654 my $page = $pdf->page;
656 # some data to layout
658 ["1 Lorem ipsum dolor",
659 "Donec odio neque, faucibus vel",
660 "consequat quis, tincidunt vel, felis."],
661 ["Nulla euismod sem eget neque.",
667 $left_edge_of_table = 50;
668 # build the table layout
674 x => $left_edge_of_table,
680 # some optional params
683 background_color_odd => "gray",
684 background_color_even => "lightblue", #cell background color for even rows
687 # do other stuff with $pdf
693 For a complete working example or initial script look into distribution`s 'examples' folder.
698 This class is a utility for use with the PDF::API2 module from CPAN.
699 It can be used to display text data in a table layout within the PDF.
700 The text data must be in a 2d array (such as returned by a DBI statement handle fetchall_arrayref() call).
701 The PDF::Table will automatically add as many new pages as necessary to display all of the data.
702 Various layout properties, such as font, font size, and cell padding and background color can be specified for each column and/or for even/odd rows.
703 Also a (non)repeated header row with different layout properties can be specified.
705 See the METHODS section for complete documentation of every parameter.
713 Returns an instance of the class. There are no parameters.
717 =head2 table($pdf, $page_obj, $data, %opts)
721 The main method of this class.
722 Takes a PDF::API2 instance, a page instance, some data to build the table and formatting options.
723 The formatting options should be passed as named parameters.
724 This method will add more pages to the pdf instance as required based on the formatting options and the amount of data.
730 The return value is a 3 item list where
731 The first item is the PDF::API2::Page instance that the table ends on,
732 The second item is the count of pages that the table spans, and
733 The third item is the y position of the table bottom.
741 ($end_page, $pages_spanned, $table_bot_y) = $pdftable->table(
742 $pdf, # A PDF::API2 instance
743 $page_to_start_on, # A PDF::API2::Page instance created with $page_to_start_on = $pdf->page();
744 $data, # 2D arrayref of text strings
745 x => $left_edge_of_table, #X - coordinate of upper left corner
746 w => 570, # width of table.
747 start_y => $initial_y_position_on_first_page,
748 next_y => $initial_y_position_on_every_new_page,
749 start_h => $table_height_on_first_page,
750 next_h => $table_height_on_every_new_page,
751 #OPTIONAL PARAMS BELOW
752 max_word_length=> 20, # add a space after every 20th symbol in long words like serial numbers
753 padding => 5, # cell padding
754 padding_top => 10, # top cell padding, overides padding
755 padding_right => 10, # right cell padding, overides padding
756 padding_left => 10, # left cell padding, overides padding
757 padding_bottom => 10, # bottom padding, overides -padding
758 border => 1, # border width, default 1, use 0 for no border
759 border_color => 'red',# default black
760 font => $pdf->corefont("Helvetica", -encoding => "utf8"), # default font
762 font_color_odd => 'purple',
763 font_color_even=> 'black',
764 background_color_odd => 'gray', #cell background color for odd rows
765 background_color_even => 'lightblue', #cell background color for even rows
766 new_page_func => $code_ref, # see section TABLE SPANNING
767 header_props => $hdr_props, # see section HEADER ROW PROPERTIES
768 column_props => $col_props, # see section COLUMN PROPERTIES
769 cell_props => $row_props, # see section CELL PROPERTIES
776 =item HEADER ROW PROPERTIES
778 If the 'header_props' parameter is used, it should be a hashref.
779 It is your choice if it will be anonymous inline hash or predefined one.
780 Also as you can see there is no data variable for the content because the module asumes that the 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.
786 # This param could be a pdf core font or user specified TTF.
787 # See PDF::API2 FONT METHODS for more information
788 font => $pdf->corefont("Times", -encoding => "utf8"),
790 font_color => '#006666',
791 bg_color => 'yellow',
792 repeat => 1, # 1/0 eq On/Off if the header row should be repeated to every new page
797 =item COLUMN PROPERTIES
799 If the 'column_props' parameter is used, it should be an arrayref of hashrefs,
800 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.
801 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.
803 Each hashref can contain any of the keys shown below:
808 {},# This is an empty hash so the next one will hold the properties for the second row from left to right.
810 min_w => 100, # Minimum column width.
811 justify => 'right', # One of left|right ,
812 font => $pdf->corefont("Times", -encoding => "latin1"),
815 background_color => '#FFFF00',
822 If the 'min_w' parameter is used for 'col_props', have in mind that it can be overwritten
823 by the calculated minimum cell witdh if the userdefined value is less that calculated.
824 This is done for safety reasons.
825 In cases of a conflict between column formatting and odd/even row formatting,
826 the former will override the latter.
832 =item CELL PROPERTIES
834 If the 'cell_props' parameter is used, it should be an arrayref with arrays of hashrefs
835 (of the same dimension as the data array) with one hashref for each cell of the table.
836 Each hashref can contain any of keys shown here:
841 [ #This array is for the first row. If header_props is defined it will overwrite this settings.
843 background_color => '#AAAA00',
844 font_color => 'blue',
850 background_color => '#CCCC00',
851 font_color => 'blue',
854 background_color => '#CCCC00',
855 font_color => 'blue',
864 In case of a conflict between column, odd/even and cell formating, cell formating will overwrite the other two.
865 In case of a conflict between header row cell formating, header formating will win.
875 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.
876 For example you can use it to put Page Title, Page Frame, Page Numbers and other staff that you need.
877 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.
878 Dont forget that your function must return a page object created with PDF::API2 page() method.
882 =head2 text_block( $txtobj, $string, x => $x, y => $y, w => $width, h => $height)
886 Utility method to create a block of text. The block may contain multiple paragraphs.
887 It is mainly used internaly but you can use it from outside for placing formated text anywhere on the sheet.
900 my $page = $pdf->page;
901 my $txt = $page->text;
907 ($width_of_last_line, $ypos_of_last_line, $left_over_text) = $pdftable->text_block(
910 #X,Y - coordinates of upper left corner
911 x => $left_edge_of_block,
912 y => $y_position_of_first_line,
913 w => $width_of_block,
914 h => $height_of_block,
916 lead => $font_size | $distance_between_lines,
917 align => "left|right|center|justify|fulljustify",
918 hang => $optional_hanging_indent,
919 Only one of the subsequent 3params can be given.
920 They override each other.-parspace is the weightest
921 parspace => $optional_vertical_space_before_first_paragraph,
922 flindent => $optional_indent_of_first_line,
923 fpindent => $optional_indent_of_first_paragraph,
925 indent => $optional_indent_of_text_to_every_non_first_line,
