-This class is a utility for use with the PDF::API2 module from CPAN.
-It can be used to display text data in a table layout within the PDF.
-The text data must be in a 2d array (such as returned by a DBI statement handle fetchall_arrayref() call).
-The PDF::Table will automatically add as many new pages as necessary to display all of the data.
-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.
-Also a (non)repeated header row with different layout properties can be specified.

-=item HEADER ROW PROPERTIES
+=item B<x> - X coordinate of upper left corner of the table. Left edge of the sheet is 0.
-If the 'header_props' parameter is used, it should be a hashref.
-It is your choice if it will be anonymous inline hash or predefined one.
-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.
+B<Value:> can be any whole number satisfying 0 =< X < PageWidth

+B<Value:> can be any whole number satisfying 0 < start_y < PageHeight (depending on space availability when embedding a table)
+B<Default:> No default value
-=item COLUMN PROPERTIES
+ start_y => 327
-If the 'column_props' parameter is used, it should be an arrayref of hashrefs,
-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.
-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.
+=item B<w> - width of the table starting from X.

+=item B<new_page_func> - CODE reference to a function that returns a PDF::API2::Page instance.
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.
For example you can use it to put Page Title, Page Frame, Page Numbers and other staff that you need.
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.

+NOTE: If 'min_w' and/or 'max_w' parameter is used in 'col_props', have in mind that it may be overriden by the calculated minimum/maximum cell witdh so that table can be created.
+When this happens a warning will be issued with some advises what can be done.
+In cases of a conflict between column formatting and odd/even row formatting, 'col_props' will override odd/even.
+
+=head4 Cell Properties
+
+If the 'cell_props' parameter is used, it should be an arrayref with arrays of hashrefs
+(of the same dimension as the data array) with one hashref for each cell of the table.
+
+Each hashref can contain any of the keys shown below:
+
=over
- # PDF::API2 objects
- my $page = $pdf->page;
- my $txt = $page->text;
+=item B<font> - instance of PDF::API2::Resource::Font defining the fontf to be used in this cell
+
+B<Value:> can be any PDF::API2::Resource::* type of font
+B<Default:> 'font' of the table. See table parameter 'font' for more details.
+
+=item B<font_size> - Font size of this cell
+
+B<Value:> can be any positive number
+B<Default:> 'font_size' of the table.
+
+=item B<font_color> - Font color of this cell
+
+B<Value:> Color specifier as 'name' or 'HEX'
+B<Default:> 'font_color' of the table.
+
+=item B<background_color> - Background color of this cell
+
+B<Value:> Color specifier as 'name' or 'HEX'
+B<Default:> undef
+
+=item B<justify> - Alignment of text in this cell
+
+B<Value:> One of 'left', 'right', 'center'
+B<Default:> 'left'
+
+Example:
+
+ my $cell_props = [
+ [ #This array is for the first row. If header_props is defined it will overwrite these settings.
+ { #Row 1 cell 1
+ background_color => '#AAAA00',
+ font_color => 'yellow',
+ },
+
+ # etc.
+ ],
+ [#Row 2
+ { #Row 2 cell 1
+ background_color => '#CCCC00',
+ font_color => 'blue',
+ },
+ { #Row 2 cell 2
+ background_color => '#BBBB00',
+ font_color => 'red',
+ },
+ # etc.
+ ],
+ # etc.
+ ];
+
+ OR
+
+ my $cell_props = [];
+ $cell_props->[1][0] = {
+ #Row 2 cell 1
+ background_color => '#CCCC00',
+ font_color => 'blue',
+ };
=back
+
+NOTE: In case of a conflict between column, odd/even and cell formating, cell formating will overwrite the other two.
+In case of a conflict between header row and cell formating, header formating will override cell.

+=item Description
+Utility method to create a block of text. The block may contain multiple paragraphs.
+It is mainly used internaly but you can use it from outside for placing formated text anywhere on the sheet.
+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.
+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.
+
+=item Parameters
+
+ $txt - a PDF::API2::Page::Text instance representing the text tool
+ $data - a string that will be placed inside the block
+ %settings - HASH with geometry and formatting parameters.
+
+=item Reuturns
+
+The return value is a 3 items list where
+
+ $width_of_last_line - Width of last line in the block
+ $final_y - The Y coordinate of the block bottom so that additional content can be added after it
+ $left_over_text - Text that was did not fit in the provided box geometry.
+
+=item Example
+
+ # PDF::API2 objects
+ my $page = $pdf->page;
+ my $txt = $page->text;
+
+ my %settings = (
+ x => 10,
+ y => 570,
+ w => 220,
+ h => 180
