restrict columns

Hi, thanks for a great module! I'm using it in a project to show bars (0-100%) with progress of all the single small tasks there is to be done by the project partners.

It would be so nice if it was possible to also restrict what columns to display with the tablemanager. That would allow for one view of a table where you get an overview (restricted number of columns), on another page one could then show the entire table shown and enter data etc.

The feature is best illustrated by:
[tablemanager:1, NULL, FALSE, colum=1 | start ="c", hide_column = 3 | 5 | 11]

so default is to show all, hide_column would, well hide the mentioned columns, show_column would only show the mentioned columns.
