Prevent Data Table from overflowing its container

[jeanpaulrsoucy]

The Data Table can overflow its container when selecting a dataset with a very long name, e.g., bc/7-day-and-cumulative-cases-by-hsda.

Adding table-layout: fixed to the CSS of the table seems to fix the overflow issue, but makes both the table and any expanded child rows very ugly and squashed. Perhaps allowing horizontal scrolling for the table is acceptable. In this case, should modify the Bootstrap class of the containing div to accommodate this.
