This property sets the height of each row in the column headings.

The value must be greater than 0 and can have decimals (e.g. 0,3).

By default rows in the column headings have an height of 1. It’s useful to increase this height when you need to display text on multiple lines in the column headings having "H" as Alignment or when you have vertical headings specified by Column-Headings-Layout.

This property replaces Row-Headings-Line-Height that is no more supported.

Example - Modify a grid to set the heading line height
