I have a Perspective table that gets data from a SQL query. Everything seems to be working except I am getting a warning about a column[0].key. What is Ignition telling me to fix?

In the `columns` array in the table’s properties, the first element (an object) has a key literally titled `key`, which the component doesn’t “know” how to parse. This was most likely caused by accidentally hitting the `+` icon inside the _object_, instead of the _array_, to add a new entry to the `columns` array.

It won’t cause any actual negative effects (the component will just ignore it, since it’s an unnecessary prop) but you can also just find it and delete it to remove the warning.

Thank you. I do hate to have warnings that I can’t explain.
