am proposing to add a Purge() method to vtkTable for the following reason:
currently, there is no direct way to clear the contents<BR>of such a table
while preserving the existing column structure. Calling Delete() results in
having to re-create the said structure, which<BR>is both inconvenient and
inefficient.<BR><BR>The proposed method would address this issue by emptying
columns while preserving the table structure.<BR><BR>Please let me know what
you think.<BR><BR>Thank you,<BR>Philippe<BR><BR>--<BR>Philippe
