support for max number of columns

Feature

I'd like a way to configure the plugin to error if we have more than a max number of columns. We have a team of ~20 people modifying csvs that should only have three columns, one of which is freeform text. Some people edit by hand, while others use this plugin. Sometimes an erroneous unquoted comma slips through. Then the next time someone uses EditCSV, we get a fourth column (or more), and on save an extra comma is added to every row. This piles up over time to create many commas (we had one csv with fifty extra commas on ~2000 rows!).

An alternative solution is to modify the write behavior to leave out dangling commas if the row has no more content in the ending columns

That's interesting, but a very specific use case.
I would rather not change the write behavior...

I could add a warning (like the messages in the bottom right corner) when a max number of columns is present when opening the table (a new setting for all csv files).
I'm not sure how much that would help though, because if you only have three columns, you would immediately see if there are more columns or is the free text is that wide?
