Is possible align the header column?

Is possible Align the Header column Vertical and Horizontal?
Horizontal (Left, Right, Center)
Vertical (Botton,middle, etc)

Because I only know the “setColAlign”, but this align the data, except the headers. In my case I need align the columns headers vertical and horizontal.

When I aply a #rspan in 2 rows, my header is located at top, and I need put in the middle of the cell merged.

Thanks. :question:

You may try to apply css styles for header cell directly when setting/attaching header line:
grid.setHeader(hdrStr, splitSign, styles);
grid.attachHeader(values, style);
You may find description in documentation here:
