Hmm... we tried this, but it doesn't seem to make any obvious difference. Is this supposed to give a speed improvement? or get around the maxnumMPgraphics limit? Thanks again for your help.

Thanks again for that! Unfortunately, when I generalize it, it takes us back to producing triple borders between adjacent cells. I think this is inevitable when overlaying a double frame (for certain sides) on top of a single frame for all sides, because a double side overlaid on a single side cannot be centered (or else the single line shows through separately from the double line). So my fix... which I'm posting here in hopes that someone may refine it, and for the benefit of others who may attempt similar things... is to center the double frames between the cells and avoid overlaying a double frame side over a single frame side. We center borders between the cells by using "enlarged" values -0.2 +/- k, i.e. center around -0.2. I'm not sure why -0.2 works better than zero, but it does... Doing this makes coincident border lines from adjacent cells look like ordinary single lines instead of being extra thick. We settled on k = 0.6 to get the desired distance between our double lines. Incidentally, I wish I knew how to put -0.2, 0.2-k, and -0.2+k into variables or something so that they could all be changed in one place, instead of hard-coded in many places. Maybe somebody can help me there. A cost of this single-overlay-per-cell approach is that we have to specify individually the 16 possible overlays (combinations of single and double edges) for any possible cell. But that's not too bad, as we only have to define them once. (In practice, we also had to define a couple of special cases where we needed some cells with open edges for a "faked rowspan". We haven't completely got those working yet.) An unexpected and potentially large benefit of this approach is that for each cell, we only generate one MPgraphic (apparently because we only use one overlay per cell), which should make the TeX run much faster, and avoid running over the maxnumMPgraphics limit. With the multiple-overlay-per-cell approach, we ended up using about 13,000 MPgraphics for our document, far beyond the default limit of 4000, and taking 15 minutes to run compared to 37 seconds for a similar document without the tables. Here is our working system... hope it's helpful to somebody: define MPgraphics for double-ruled tables % Lars Huttar, 2008-12-09 % Thanks to Wolfgang Schuster on NTG-list % Ea

(I looked up some Metapost references but couldn't find a definition of "enlarged".) But it seems to work: the double lines between two cells overlap exactly, so you get a consistent look. However, when I try to mix double frames with single frames, I'm having trouble.

See http://www.huttar.net/lars-kathy/tmp/test-mp-tableframe.pdf, second table. Also, on the side that has double lines, the double lines don't go all the way to the top and bottom (see same pdf, second table), so that the double line is not continuous across multiple rows. Any suggestions?

We have been told that in TeX, or at least in ConTeXt, you can't do double rules (we'd be happy to be corrected on that point), so we have been trying to use thick and thin lines to show grouping. Thick or thin lines work fine if applied to whole tables or whole cells, but when there are cells with thick rules on some sides and thin rules on other sides, it gets confused. For example, we tried (a)\setupTABLE[c][4][leftframe=on,rulethickness=0.5mm] to set the left border of the fourth column to be thick. This worked. But then if we use (b)\setupTABLE[c][4][rightframe=on,rulethickness=0.25mm] to set the right border of the same column to be thin, it overrides the thickness of both left and right borders, so setting (a) is lost. In other words, we can't seem to get a given cell to have a thick border on one side and a thin border on the other side. (Well, we could fake it in some cases by setting rulethickness for an adjacent cell, but that adjacent cell would then have to have thick borders on all sides.)

Incidentally, if you set the bottom border of row 1 and the top border of row 2 each to be thick, the result is additive: you get a doubly-thick border.
