[Mono-list] TreeView question

[Rodney J. Dyer]

OK, I'm attempting to implement a spreadsheet-like interface using gtk#
and I'm having a tough time.  Can someone point me in the direction of
an example/tutorial of using ListStore/NodeStore for a TreeView with a
variable number of columns.  I'm looking at the user importing a
tab-delimited text file, say from a spreadsheet program or something and
manipulating it in various ways.  The number of columns is resolved when
the user imports a data file, not at design time so things such as: 

[TreeNode (ColumnCount=2)]

and 

[TreeNodeValue (Column=1)]

cannot be determined at compile time.  An example or quick point in the
right direction would be appreciated.

Thanks,
