Hide a Numbers table with an if/then formula?

There's no way I'm aware of to do this. You might get somewhere close with conditional formatting to format the table to appear blank (e.g. white text on a white background), but that's non-trivial, and the data would still be accessible, not truly hidden.

The closest I can think of is a filter that filters out all the rows, one such as "show rows where column B cell is TRUE". The table won't disappear completely, though. If it has a header row, that row will remain. If not header row you'll end up with a "row" that says "No rows match the filter conditions".

...And, for this example, column B would be a formula like =Table 2::$B$1 where that cell is a checkbox you can check/uncheck to hide the table
