* @ecell: the renderer to be used for this column
* @compare: comparision function for the elements stored in this column
*
* The ETableCol represents a column to be used inside an ETable. The
* ETableCol objects are inserted inside an ETableHeader (which is just a
* collection of ETableCols). The ETableHeader is the definition of the
* order in which columns are shown to the user.
*
* The @text argument is the the text that will be shown as a header to the
* user. @col_idx reflects where the data for this ETableCol object will
* be fetch from an ETableModel. So even if the user changes the order
* of the columns being viewed (the ETableCols in the ETableHeader), the
* column will always point to the same column inside the ETableModel.
*
* The @ecell argument is an ECell object that needs to know how to
* render the data in the ETableModel for this specific row.
*
* Data passed to @compare can be (if not %NULL) a cmp_cache, which
* can be accessed by e_table_sorting_utils_add_to_cmp_cache() and
* e_table_sorting_utils_lookup_cmp_cache().
*
* Returns: the newly created ETableCol object.
