86  * e_table_col_new:
87  * @spec: an #ETableColumnSpecification
88  * @text: a title for this column
89  * @icon_name: name of the icon to be used for the header, or %NULL
90  * @ecell: the renderer to be used for this column
91  * @compare: comparision function for the elements stored in this column
92  *
93  * The ETableCol represents a column to be used inside an ETable.  The
94  * ETableCol objects are inserted inside an ETableHeader (which is just a
95  * collection of ETableCols).  The ETableHeader is the definition of the
96  * order in which columns are shown to the user.
97  *
98  * The @text argument is the text that will be shown as a header to the
99  * user. @col_idx reflects where the data for this ETableCol object will
100  * be fetch from an ETableModel.  So even if the user changes the order
101  * of the columns being viewed (the ETableCols in the ETableHeader), the
102  * column will always point to the same column inside the ETableModel.
103  *
104  * The @ecell argument is an ECell object that needs to know how to
105  * render the data in the ETableModel for this specific row.
106  *
107  * Data passed to @compare can be (if not %NULL) a cmp_cache, which
108  * can be accessed by e_table_sorting_utils_add_to_cmp_cache() and
109  * e_table_sorting_utils_lookup_cmp_cache().
110  *
111  * Returns: the newly created ETableCol object.
