[Designer] Broken design on Tables - no responsiveness

Problem Description

The expectations of the provided Card JSON is to render a table of three columns, third column always shown, second column shown only on devices of width at least standard, first column shown on devices of width at least narrow.
So in preview mode, for Very Narrow, we should see only third column, for Narrow we should see first and third columns, on Standard and Wide we should see all columns

Screenshot

The issue names no implementation file or test; start by loading the provided Card JSON in Designer preview at Very Narrow, Narrow, Standard, and Wide widths. Trace the table responsiveness behavior and verify that only the third column appears at Very Narrow, the first and third at Narrow, and all three at Standard and Wide.
