Resize column widths with mouse in TreeView & TableView & Grid

Would be nice to be able to resize column widths in the FMX TreeView, TableView and GridViews by dragging the line seperating the columns... similar to most grid controls... (excel, etc).


This feature should already be available, for the TTMSFMXGrid under Options.Mouse.ColumnSizing for the TTMSFMXTreeView under Interaction.ColumnSizing

This feature was implemented.
