            Description

            An ace:dataTable uses header column grouping, the table has a total of 6 columns. The top most header group displays three columns with col spans of 3, 2 and 1. When the table is set to be scrollable, the columns are rendered out of alignment.

            In debugging the datatable.js in Chrome I see an error thrown:

            datatable.js.jsf:343 Uncaught TypeError: Cannot call method 'children' of undefined

            This error causes the column width calculations to exit and therefore the columns are rendered misaligned. The cause of the error seems to be usage of a header group column using a colspan=1

              Fixed in r26294
              Changed assumption that we will find the same number of single colspan header cols, to that the single colspans on the lowest rows are those corrolated with the table columns, and to truncate any unnecessary header columns from the beginning of the selection.

              Add TLD doc explaining requirements for scrolling and columnGrouping.
