[Solved] Diagonal lines in table cell

#1

I need to draw a table with two parameters, which is typically presented with a diagonal line in the first cell of the first line, for example, the following table.

I wonder if we can draw the diagonal easily in TeXmacs. I appreciate any help you can provide.

Not that I know of but you can use ‘Draw->Ink here’ to insert a graphical overlay and draw a line and the text in the graphical environment. Or even more easily, introduce a graphics environment in that cell and place the elements in the graphics.

An example (copy here and “Paste from… -> TeXmacs”):

One of deficits of this method is that it is very fragile when the other cells are modified. See the following code:

<\wide-block>
  <tformat|<cwith|1|1|1|1|cell-halign|l>|<cwith|1|1|1|1|cell-width|4cm>|<cwith|1|1|1|1|cell-hmode|exact>|<cwith|1|1|1|1|cell-lsep|0em>|<cwith|1|1|1|1|cell-rsep|0em>|<cwith|1|1|1|1|cell-bsep|0em>|<cwith|1|1|1|1|cell-tsep|0em>|<table|<row|<\cell>

Sure. It was a 30 sec hack. you cannot expect too much from it.
