This cannot be done with a uitable for traditional figures.
uitable for traditional figures implement menus by setting the entry for ColumnFormat to be a cell array of character vectors. Then the individual cell entry for the contents must be a scalar integer that is the index of into the cell array of character vectors. Because it is the same reference cell array each time, it is not possible to have one row activate one menu and a different row activate a different menu.
Perhaps you could get somewhere with the Java level described by Yair in undocumentedmatlab.com
