Hi there,

That's the solution I'd actually implemented, but I realized that it's

very common to have the first row using colspan > 1 to provide a large

heading, so the first row gives a false account of the number of cells

per row. However, what I think I'll do is count the cells in each row,

then use the largest number.

What I'm doing is very similar to what you had to do; I'm reading XHTML

(which is XML) using the XDOM libraries, and reconstructing a document

from it. It's hard, but it's going to be cool when I get it working. I'm

going to be able to use XHTML as my document storage format, with CSS

handling all the styles.

Cheers,

Martin
