How can I specify a td tag should span all columns (when the exact amount of columns in the table will be variable/difficult to determine when the HTML is being rendered)? w3schools mentions you can use colspan="0", but it doesn't say exactly what browsers support that value (IE 6 is in our list to support).
It appears that setting colspan to a value greater than the theoretical amount of columns you may have will work, but it will not work if you have table-layout set to fixed. Are there any disadvantages to using an automatic layout with a large number for colspan? Is there a more correct way of doing this?

Just use this:
It works on Firefox 3.6, IE 7 and Opera 11! (and I guess on others, I couldn't try)
Warning: as mentioned in the comments below this is actually the same as
colspan="100". Hence, this solution will break for tables with csstable-layout: fixed, or more than 100 columns.
