664 PDF::Table - A utility class for building table layouts in a PDF::API2 object.
671 my $pdftable = new PDF::Table;
672 my $pdf = new PDF::API2(-file => "table_of_lorem.pdf");
673 my $page = $pdf->page;
675 # some data to layout
677 ["1 Lorem ipsum dolor",
678 "Donec odio neque, faucibus vel",
679 "consequat quis, tincidunt vel, felis."],
680 ["Nulla euismod sem eget neque.",
686 $left_edge_of_table = 50;
687 # build the table layout
693 x => $left_edge_of_table,
699 # some optional params
702 background_color_odd => "gray",
703 background_color_even => "lightblue", #cell background color for even rows
706 # do other stuff with $pdf
712 For a complete working example or initial script look into distribution`s 'examples' folder.
717 This class is a utility for use with the PDF::API2 module from CPAN.
718 It can be used to display text data in a table layout within the PDF.
719 The text data must be in a 2d array (such as returned by a DBI statement handle fetchall_arrayref() call).
720 The PDF::Table will automatically add as many new pages as necessary to display all of the data.
721 Various layout properties, such as font, font size, and cell padding and background color can be specified for each column and/or for even/odd rows.
722 Also a (non)repeated header row with different layout properties can be specified.
724 See the METHODS section for complete documentation of every parameter.
732 Returns an instance of the class. There are no parameters.
736 =head2 table($pdf, $page_obj, $data, %opts)
740 The main method of this class.
741 Takes a PDF::API2 instance, a page instance, some data to build the table and formatting options.
742 The formatting options should be passed as named parameters.
743 This method will add more pages to the pdf instance as required based on the formatting options and the amount of data.
749 The return value is a 3 item list where
750 The first item is the PDF::API2::Page instance that the table ends on,
751 The second item is the count of pages that the table spans, and
752 The third item is the y position of the table bottom.
760 ($end_page, $pages_spanned, $table_bot_y) = $pdftable->table(
761 $pdf, # A PDF::API2 instance
762 $page_to_start_on, # A PDF::API2::Page instance created with $page_to_start_on = $pdf->page();
763 $data, # 2D arrayref of text strings
764 x => $left_edge_of_table, #X - coordinate of upper left corner
765 w => 570, # width of table.
766 start_y => $initial_y_position_on_first_page,
767 next_y => $initial_y_position_on_every_new_page,
768 start_h => $table_height_on_first_page,
769 next_h => $table_height_on_every_new_page,
770 #OPTIONAL PARAMS BELOW
771 max_word_length=> 20, # add a space after every 20th symbol in long words like serial numbers
772 padding => 5, # cell padding
773 padding_top => 10, # top cell padding, overides padding
774 padding_right => 10, # right cell padding, overides padding
775 padding_left => 10, # left cell padding, overides padding
776 padding_bottom => 10, # bottom padding, overides -padding
777 border => 1, # border width, default 1, use 0 for no border
778 border_color => 'red',# default black
779 font => $pdf->corefont("Helvetica", -encoding => "utf8"), # default font
781 font_color_odd => 'purple',
782 font_color_even=> 'black',
783 background_color_odd => 'gray', #cell background color for odd rows
784 background_color_even => 'lightblue', #cell background color for even rows
785 new_page_func => $code_ref, # see section TABLE SPANNING
786 header_props => $hdr_props, # see section HEADER ROW PROPERTIES
787 column_props => $col_props, # see section COLUMN PROPERTIES
788 cell_props => $row_props, # see section CELL PROPERTIES
795 =item HEADER ROW PROPERTIES
797 If the 'header_props' parameter is used, it should be a hashref.
798 It is your choice if it will be anonymous inline hash or predefined one.
799 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.
805 # This param could be a pdf core font or user specified TTF.
806 # See PDF::API2 FONT METHODS for more information
807 font => $pdf->corefont("Times", -encoding => "utf8"),
809 font_color => '#006666',
810 bg_color => 'yellow',
811 repeat => 1, # 1/0 eq On/Off if the header row should be repeated to every new page
816 =item COLUMN PROPERTIES
818 If the 'column_props' parameter is used, it should be an arrayref of hashrefs,
819 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.
820 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.
822 Each hashref can contain any of the keys shown below:
827 {},# This is an empty hash so the next one will hold the properties for the second row from left to right.
829 min_w => 100, # Minimum column width.
830 justify => 'right', # One of left|right ,
831 font => $pdf->corefont("Times", -encoding => "latin1"),
834 background_color => '#FFFF00',
841 If the 'min_w' parameter is used for 'col_props', have in mind that it can be overwritten
842 by the calculated minimum cell witdh if the userdefined value is less that calculated.
843 This is done for safety reasons.
844 In cases of a conflict between column formatting and odd/even row formatting,
845 the former will override the latter.
851 =item CELL PROPERTIES
853 If the 'cell_props' parameter is used, it should be an arrayref with arrays of hashrefs
854 (of the same dimension as the data array) with one hashref for each cell of the table.
855 Each hashref can contain any of keys shown here:
860 [ #This array is for the first row. If header_props is defined it will overwrite this settings.
862 background_color => '#AAAA00',
863 font_color => 'blue',
869 background_color => '#CCCC00',
870 font_color => 'blue',
873 background_color => '#CCCC00',
874 font_color => 'blue',
883 In case of a conflict between column, odd/even and cell formating, cell formating will overwrite the other two.
884 In case of a conflict between header row cell formating, header formating will win.
894 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.
895 For example you can use it to put Page Title, Page Frame, Page Numbers and other staff that you need.
896 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.
897 Dont forget that your function must return a page object created with PDF::API2 page() method.
901 =head2 text_block( $txtobj, $string, x => $x, y => $y, w => $width, h => $height)
905 Utility method to create a block of text. The block may contain multiple paragraphs.
906 It is mainly used internaly but you can use it from outside for placing formated text anywhere on the sheet.
919 my $page = $pdf->page;
920 my $txt = $page->text;
926 ($width_of_last_line, $ypos_of_last_line, $left_over_text) = $pdftable->text_block(
929 #X,Y - coordinates of upper left corner
930 x => $left_edge_of_block,
931 y => $y_position_of_first_line,
932 w => $width_of_block,
933 h => $height_of_block,
935 lead => $font_size | $distance_between_lines,
936 align => "left|right|center|justify|fulljustify",
937 hang => $optional_hanging_indent,
938 Only one of the subsequent 3params can be given.
939 They override each other.-parspace is the weightest
940 parspace => $optional_vertical_space_before_first_paragraph,
941 flindent => $optional_indent_of_first_line,
942 fpindent => $optional_indent_of_first_paragraph,
944 indent => $optional_indent_of_text_to_every_non_first_line,
