Stretching width in natural TABLEs
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
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 On Sep 2, 2012, at 12:24 PM, Aditya Mahajan wrote:

\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. Aditya

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.

Ah, thats makes more sense. I was so happy to see the right ratio of the widths, that I did not notice that.

Thanks. I'll play around with it tomorrow. Aditya

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.
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.

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