Tab-Widths
This property is used to set the width, in cells, of the tab identified by the 
Tab-Index property.
The tab width is applicable only to Tab-Controls with the 
Tab-Flat style and without the 
Accordion style.
When values are enclosed between parentheses, the 
Tab-Index property is ignored, the 1st value refers to the 1st panel, the 2nd value refers to the 2nd panel and so on.
