Write HTML tables
InformationsAuthor: Rick van Buuren
License: Freeware
DescriptionThis script allows you to parse HTML tables to PDF Cells (and has got some other
functionality too).
It can parse:
<table border="border">
where border can be 1 or 0
<tr>
which makes a new row
<td width="width" height="height" bgcolor="bgcolor">
where width and height are integers and bgcolor is html color code
It's a really simple script. Inner tags can give some problems; <td><b>big</b> small<td>
won't give a proper output for example. It also doesn't place pictures in a correct way, although you
can use a table to align a picture:
<table><tr><td width="200"> </td><td width="200"><img src="..." width="..." height="..."></td></tr></table>
will align a picture in the middle.
You need to use when you want a blank cell.
