Is there a way to override the wpDataTableFilterSection class? I have placed desired formatting in the wpdatatable settings CSS section but not applying.  I am trying to remove all the unnecessary margins.

wpDataTableFilterSection {
    float: left;
    /* margin-bottom: 10px; */ or /* margin-bottom: 0px; */
    margin-right: 15px;
    width: 160px;
    /* min-height: 115px; */ or /* min-height: 0px; */
}

If needed i can change the source wpdatatable CSS but would prefer not to.

Thanks

Thanks but not working.  I did solve but not the right solution.  If i include the below in the page right before the table short code it works. Note: my page only displays the filters, no table.  Then i have "linked" charts below the filters so that applying filters updates all the linked charts.  

As a separate, unrelated comment, it would be super nice to have grouping in charts to perform an average instead of always summing.  This would allow ratios on the data.  An option to pick average or sum would greatly enhance the functionality of this awesome product.

<style>

/* need to override class to eliminate select margin spacing - NOT WORKING */
.wpDataTableFilterSection {
    float: left !important;
    /* margin-bottom: 10px; */ or /* margin-bottom: 0px; */
    margin-right: 15px !important;
    width: 160px !important;
    /* min-height: 115px; */ or /* min-height: 0px; */
}
</style>

I think the wpdatatable custom css is not being placed before the filters when in the header.  Or i'm missing something else.

A cleaner solution would be beneficial.  

Thanks
