6a96aa54cfbf2efbe12971426581eacfa9d9be6e Fix: Sizing of columns when scrolling is enabled

Need to set a min-width so the columns widths don't collapse down.

This is a continuation of DataTables/DataTablesSrc@fdc8a7f#diff-3ef3d2eb10c8d1c4610fb67d6ae25612f3b94e564a217f4f8cae634eb17731b4R165

and
DataTables/DataTablesSrc@3c4df03
.

None have yet covered all bases. This appears to work okay for the
testing done locally so far. Deploying to nightly for test
