       There are two different meanings to the word "column". The first

-      type of data. This is very much like the usage in a database
-      table where a column is a field in the database.
+      is the model column (defined by the &ETableCol: object). A model
+      column describes how it maps to the column in the &ETableModel;

+      resizability, resize dimensions, and a renderer for this

+      &ETable; distinguishes between a model column index, and a view

-      The second type of column is a view column. A view column
