This property applies a line break on the text of an E3Browser's column headers, allowing to display the full text of a column's name. That line break is applied only where there is a space, a tab, or a forced line break on the text. Configuring this property in True does not change the value of the FixedRowHeight property, which controls the height of column headers. In case the header text does not contain spaces, tabs, or forced line breaks, that text is truncated and an ellipsis is displayed on the limit of the column's width. In addition, the vertical alignment of the text, which is usually centered, is changed to a top alignment. Default value of this property is False.
