I'm writing a program to create a drawing list as an acad table. I needed a header for CIVIL, ARCHITECTURAL, STRUCTURAL etc., that can occur anywhere up and down the table, not just the top. I have found that two rows can be merged, and this works for me. One problem I can't resolve however. (all units are mm) When I merge two 8mm rows I get 18.66667, not the 16.0000 I expected. Because I will have several tables across the A0 sheet, I need the outlines to line up. Even explicitly setting the row height (after the merge) the height remains at 18.66667. Is there some "invisible" value added to merged cells?
