It's not hard to script this sort of thing.
But the minimum height is a minimum height. Why do you need to increase it by p7 sometimes?
If you can articulate the clear rules for exactly waht you want to happen, we can give you a script.
A screenshot might help.
(So might posting in the scripting forum)
Ah, I did not think about scripting it. That might be a solution indeed.
The reason why we would need 7pt increments is that multiple lines orften won't fit in a 14pt cell hight. And most designs call for a grid to work in.
So what I would want to happen is a hight of an empty cell to be 7pt.
The hight of a cell with content to be a minimum of 14pt, unless this cell contains multiple lines it should increase by 7pt till it can fit all content (and decrease by 7pt if a line is removed in an update of the .xls file).
A cell with a certain Cell-style to have a hight of 21pt.
Hope the attached example helps.
I will also post it in the scripting section, but perhaps leave it here till there is a solution? So others that, like me, fail to think of scripting will also find it.
