To use the column roles, you have to set the column property. Typically
this is done when creating the DataTable, but using the arrayToDataTable
method bypasses that. I believe you can call the setColumnProperty method
of the DataTable to set the column role, something like this should do it:
data.setColumnProperty(5, 'role', 'tooltip');
