Column Collections

The FlexGrid control has two sets of columns:

Fixed Columns: This collection contains the columns on the left of the grid.

Scrollable Columns: This collection contains the main set of columns.

Both column collections are ColumnCollection objects, which extend regular arrays. You may add or remove columns by adding or removing Column objects from these arrays.
