Hi,
I have a SWT Table with several columns, and changing datasets to be displayed in the Table. There seems not to be a method to remove Columns from a Table, which I need for clearing and refilling the Table with new data.
I found out, that disposing the Columns works. But isn#t that a bit too brutal? I need to remove them, just as TableItems can be removed by index.
If this isn't possible, please explain :/ and if you can image a workaround, tell me, too 
Thanks

Disposing the column is the right thing to do. Some might suggest to set
the width to 0, but this is clearly a different thing. E.g. we have
written our own table configuration dialog which allows users to
change settings of individual columns (e.g. sort order, enablement,
disablement, etc.). If the column has not been disposed, it's still
part of the table.

Can you present an example? A short view on another SWT component
(TabFolder) with TabItems shows that it follows the same style as
Table with TableColumns.
