Remarks

Use conditions

<Table>.EnumColumn can be used on:

a browsing or memory control,
a single-selection or multiselection control,

Reminder: Multiselection controls are available in Ajax only

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 <Table>.ColumnSubscript.

These subscripts are different if the columns have been moved by the user.

<Table>.EnumColumn is using the creation subscript of the column.
