Scrollbar in header row in firefox with scrollx

derekws

1) The scrollbar in the red circle only appears in firefox, when using scrollx. How can I get rid of it?
2) How can I get rid of the padding/margin (in purple) to the left and right of the table? Where is that coming from? It only appears on my datatables, not my others.

I got rid of the scrollbar using:

.DTFC_RightWrapper {
display:none;
}

but that seems like a bug worth fixing.

The other issue I worked around by placing the table in its own col with p-0 in its own row, but again, shouldn't have to do that.
