Whenever I use
, I get the following error:
Uncaught TypeError: Cannot set property \'_DT_CellIndex\'
You can hack around the lack of colspan support by adding an "invisible" cell for every cell that's eliminated:
Wide column
Normal column
Normal column
Normal column
DataTables doesn't complain, the table renders normally and sorting works (invisible columns sort as the empty string).
I haven't tried this with rowspan.
