Support line breaks and tab replacement in tabular table values (#182)

mrsdizzie · web-flow · commit 1556134a2b22 · 2025-03-04T17:39:14.000+01:00
This adds the same functionality from both #179 and #181 to the tabular table output. In WP CLI behat tests, the 'table containing rows' check can only use tabular output so we need to fix it here in order for tests to work.
