Quick comments on the plugin:

• I noticed it uses BeautifulSoup to parse the HTML, modify it, and re-dump it. This is highly inefficient in a MkDocs setup (not blaming anyone, it's just how it is). The efficient way of doing this is with a Markdown extension that operates on the HTML (converted from Markdown) directly, to avoid re-parsing and re-dumping by each plugin. It would use a TreeProcessor (I'll let you look at their docs if you're interested in the switch). Note that a Markdown extension would only work on hard-coded tables, or tables generated by other Markdown extensions, but not table generated by other MkDocs plugins, so the switch might not be possible depending on your use-case.
• Your README mentions removing rows of tables, but after reading the code, to me it looks like it removes columns corresponding to the keyword you specify, not rows: it removes the corresponding cell from the table headers, and the cells at the same index from all rows. So it effectively removes the column (vertical). Or did I misunderstand ☺️?
