SWT TableViewer table header height

Table

Suitable under SWT

, and on the other TableViewer

is under JFace

. So it's not clear if you need a solution for TableViewer

or Table

. Also, in the absence of any piece of code on your part, I want to demonstrate it for JFace

and TableViewer

, although the concept will remain the same for Table

and SWT

.

→ Before installing the font

→ After setting the font

You can see the difference in the heights of the headings.
