<Column subscript>: Integer
Subscript of the column, included between 1 and the number of columns found in the Table control + 1.
A WLanguage error occurs if this parameter is greater than the number of columns found in the Table control + 1.
To find out the number of columns in a Table control, use TableCount.
Remarks

Use conditions

TableEnumColumn can be used on:
  • a browsing or memory control,
  • a single-selection or multiselection control,
WEBDEV - Server codePHP Reminder: Multiselection controls are available in Ajax only
WEBDEV - Server codePHP Reminder: Multiselection is not available for "classic" Table controls.

The different types of column subscripts

Two types of subscripts are available for the columns:
  • Subscript of the visible position: subscript of the column when running the window.
  • Creation subscript: subscript of the column when creating the control in the window editor.
These two types of subscripts are returned by TableColumnSubscript.
These subscripts are different if the columns have been moved by the user.
TableEnumColumn is using the creation subscript of the column.
