Could you give a little more info about what you are trying to do?  

A treemodel has a fixed number of columns, so there will always be n entries
in each row, where n is the number of columns in the treemodel.  Some of
these entries, of course, may contain NULL, zero, or empty values.

When you set up your treeview, you need to specify which renderers are
associated with which columns of the treemodel.  To specify visibility on a
row-by-row basis, you could add a boolean column or columns to your
treemodel and associate this with the "visible" flag for the "data" column.
In your case, it sounds like you want a visibility column for each "data"
column (or perhaps only for each optional row if there is a fixed minimum
number of visible entries in a row.)
