Hi,
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.
Extreme tables implement something similar using option={stretch, width},
but AFAIU, it is not possible to fix the width of a particular column.
Aditya

Ah, thats makes more sense. I was so happy to see the right ratio of the widths, that I did not notice that. > The hack: Thanks. I'll play around with it tomorrow.

It's just I had the same problem last week, and a deadline made me settle for the ad hoc approach. I was trying to solve the same situation several week ago. Finally, I measured what the "fit" option of the first column mean in real units (cm) and I altered widths of remaining columns to get \textwidth in total, which is ugly and non-systematic solution. So it seems that there is a task for natural TABLEs: " Suppose one or more columns have "fit" width, so the width is computed at run-time. Suppose the total width of the table is defined, too. How to specify width of other columns to have a specified ratio? " E.g.: col1.width="fit" -> will be a concrete value at run-time, 'col1.width.real' col2.width="fit" -> will be a concrete value at run-time, 'col2.width.real' TABLE.tot.width=\textwidth col3.width."weight"=1 col4.width."weight"=2 should give col3.width = (TABLE.tot.width - col1.width.real - col2.width.real) / (col3.width."weight" + col4.width."weight") * col3.width."weight" col4.width = (TABLE.tot.width - col1.width.real - col2.width.real) / (col3.width."weight" + col4.width."weight") * col4.width."weight" Best regards, Lukas -- Ing.

I notice that \setupTABLE[c][1][width=fit] \setupTABLE[c][2][width=broad] \setupTABLE[c][3][width=broad] splits the remaining space equally between columns 2 and 3. So, after starting at the code of pack-rul for a while, I realized that \setupTABLE[c][1][width=fit] \setupTABLE[c][2][width=0.33\hsize] \setupTABLE[c][3][width=0.66\hsize] should work and it does! Now if someone could explain WHY it works, I'll be enlightened.
