Column Header
Definition
The column header displays the name of a column for the user. You are able to define three different texts as column header.
Use
You are able to make the following settings for the column header:
· Determine wording of the column header
· Display or hide column header
· Determine whether the user can sort the table according to this column by clicking on the column header
· Determine tooltip for the column header
· Display an icon (only tree structure)
Determine Wording of the Column Header
The column header is a property of the COLUMN object. In this way you are able to specify the column header for every column in the internal data table.
You can specify three different variants of the column header: The long, medium and short column header. If the user changes the column width, the column header that fits the column best is automatically used.
A special case is the column header of the hierarchy column in the tree structure: Because there is no COLUMN object for this column, you determine this column header using the properties of the tree structure.
