I am trying to dynamically allocate the height of rows in a table based upon a number, specifically the number of minutes that are devoted to a specific activity in a class lesson. The table represents the lesson plan which is broken up into parts, a large row indicates a longer activity, and a short row a short activity etc. I can see how to adjust the row height by using \[2em] at the end of the row, but I would rather calculate this value from item 1, since the row height should be proportional to the number of minutes in the activity, I also calculate a running total so that the teacher can easily when each part of the lesson starts, durring the hour, and that works fine.enter image description here

See the definitions for \R, I have been strugleing with this for a few days and not getting anywhere, any help would be greatly appreciated.

All that I did was to add a \rule[\dimexpr9pt-#1\hunits\relax]{0pt}{#1\hunits} to the 1st column definition of \R, where \hunits was chosen to meet the overall height (time) constraints. In this case, \hunits is set to 3.5 pt, meaning each minute of your lesson gets 3.5pt of vertical space.

Note that if a multiline cell like "Learning Activities" is too long, it could (and does) overwhelm the vertical height set by the rule. I show this below by making the rule 1pt in width:

  • Thakns very much for that answer Steven, I have been struggleing with this problem all day, and my solution is very messy. I was also using rule once I figures out exactly what a rule was. I think it is probably fine or even better to have an overrun. Aug 29 '14 at 10:35
