Primary look not applied to Excel button

[novvere]

A dataTable with the attribute look="primary" applies correct style to all the data table but the predefined export buttons maintains the default style.

Is there any way to apply a different style to these buttons?

Wel, I realized there are no look attribute on dataTable it's just not used at all.

The problem is the spacelab theme have different colors for pager (blue) and predefined export buttons (dark grey).

I will change to default theme.
