datatables - jQuery dataTables - minimum column width and table horizontal scroll

Question

I'm having two issues with Datatables. First, I need to choose a minimum column width and if the content is bigger, the column must be resized to the content width.

And, I'm trying to use the following code to have horizontal scrollbars, but it's causing problems with the size and positioning of the header cols and the content cols.

$(".dataGrid").dataTable({
    "bJQueryUI": true,
    "sPaginationType": "full_numbers",
    "sScrollX": "100%",
    "sScrollXInner": "110%",
    "bScrollCollapse": true
});
