SuppressHdr: Suppress Grid Headers

Description

Suppress grid headers

Possible values are:

	0	Headers not suppressed.
	1	Row header suppressed (left side).
	2	Column header suppressed (top).
	3	Both headers suppressed.

Suppression is done by setting the header height/width to 0. When not suppressed, the height/width will return to the last value.

(The SuppressHdr property was added in PxPlus 2020.)
