Different text-align for cells and column header

If I provide a text align for a column, like the following:

.active-column-0 {
    text-align: right;
}

the header is automatically aligned in the same way. Aligning right is nice for numbers, but I still would like to see the column header beeing aligned to the left, or maybe centered.

Is there a way to define a different text-align for the column header?

How do I find the style that defines the text orientation for the column header?

I would like to have for example column headers centered but then depending on the column type numbers right aligned, text left aligned, etc.

Found the answer!
