gum format: Long text in Markdown table breaks formatting for all cells

[hxlnt]

Describe the bug
When text in the cell of a Markdown table is longer than what can be shown on one line, the line wraps across the whole table rather than within the cell. This breaks formatting for the entire table.

To Reproduce
Steps to reproduce the behavior:

1. Create a Markdown file with a table that has long text

Expected behavior
Long text wraps within the cell, and table formatting is preserved
