Is it possible to stretch the widths of each column in natural TABLEs, so that the widths are in a certain propotion? For example, suppose I have a table with three columns and I want to set the width of the first column to a fixed amount, and split the remaining space between columns two and three in a 1:2 ratio.
If you know the width of the first column and total width, then you can use arithmetic, as in the example below. But perhaps this already occurred to you, and you were wondering if the widths and stretching can be handled automatically -- the short answer is I don't know.
\starttext \setupTABLE[c][1][width={2cm}] \setupTABLE[c][2][width={\dimexpr(\textwidth-2cm)/3\relax}] \setupTABLE[c][3][width={\dimexpr(\textwidth-2cm)* 2 / 3\relax}] \startTABLE \NC One \NC Two \NC Three \NC\NR \NC A \NC B \NC C \NC\NR \stopTABLE \stoptext
Apart from being hard to maintain, this works well if I know the width of a cell in advance. But most of the time I want something the width of the fixed column to be determined using width=fit option, so I cannot precompute the width of other columns.

That's what I was afraid. It's just I had the same problem last week, and a deadline made me settle for the ad hoc approach. You made me curious enough to go look at the source, and one can hack it to work. See below, if interested. Not optimal, and might break in future. By the way, what you posted in your other message,
\setupTABLE[c][1][width=fit] \setupTABLE[c][2][width=0.33\hsize] \setupTABLE[c][3][width=0.66\hsize]
extends into the right margin by the width of the first column or thereabouts, for me.

Maybe not worth doing, though...maybe harder than I think -- the table stuff is complicated, and I'm assuming that since it worked once, I haven't messed anything up. ________________________________ This e-mail message (including any attachments) is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
