Joined Data Table Error Message

If there is an error in the join definition, the Join icon or Left/Right Column drop-down is marked with a red border. Consequently, the preview is not displayed.

For example, if the join keys have different data types, an error message is displayed:

“A panopticon.developer.tables.standalone.TimeColumn column from the left table in the join is not compatible with a panopticon.developer.tables.standalone.NumericColumn column in the right.”

Make the necessary changes to make the join work.
