Graphics, Figures & Tables ⇒ Missing borders when using multirow and multicolumn?

[cdrjameson]

I am attempting some simple exercises from an old Latex manual and I have reproduced a table except the bottom right cell is missing the bottom half of the right border.

The cell is a nested multirow within a multicolumn declaration, that is, it is effectively a 2x2 cell with borders around the sides. The bottom half of the cells right border is missing like this:



Here is my code; I believe the error will be somewhere in the second to last declaration.

Code: Select all

My original code didn't have enough &s to fill the table. I solved this by adding an empty multi-column box as the last cell. This then created the border line as expected. Previously no border was being created I presume becasue the environment hadn't seen enough cells being filled.

The last line of the previous code has changed to

Code: Select all

&&Conf.~Room&&Conf.~Room&\multicolumn{2}{c|}{}\\ \cline{1-7}
