There is only one commandLink on your page, not one per column and row
(or #{bean.rows}" multiplied #{bean.columns} in your case). If you
need to get the column name, you need to ask the t:columns component
for that information.
Use the binding attribute on your dataTable and your columns
components, and then do a "columns.getRowData()" [getRowData is NOT a
typo] to get the column object ("col") and "dataTable.getRowData()" to
get the row object ("g") inside your action method. Probably
something like
"((java.util.Map)dataTable.getRowData()).get(((COLUMN_TYPE)columns.getRowData()).getName())
