Add ATTR_COLUMN_VISIBLE attribute for table columns

[vix]

The additional columns of a tree can be hidden using SetTreeColumnAttribute() with ATTR_COLUMN_VISIBLE parameter. This is an easy and effective way.

For a table this attribute isn't supported, so you can use some workaround that requires more coding and have some disadvantages (for example if you set the width to the minimum value of 1, the user can increase it with the mouse...).

I think that the ATTR_COLUMN_VISIBLE parameter would solve this needs in the perfect way.

I second this suggestion because it is so much easier setting up a full table in the UI editor and then only use (i.e. show) some of the columns rather than assembling a table programmatically...
