Remove scrollbar from table element

Table element whose column widths are specified to sum up to 100% displays a scrollbar and a very wide blank after the last column when these two conditions are met (removing either one of them gets rid of scrollbar and blank):

  • Data table is empty
  • Placement of the container is small enough (in my case the scrollbar appears as soon as container width is below ~400px)
(Using flexgrid)

I have exactly the same issue (using our old grid). Any ideas to solve this?
