I am trying to delete several columns at once by sending the command **deleteColumn** , but it only deletes the column that refers to the first item of the **arguments** array. Do have I have to send an independent command for each individual column I want to delete? Is there a single command to delete all columns and data, i.e. to clear the table completely?
`{"command": "deleteColumn", "arguments": ["event", "active", "trigger"], "returnPromise": false}`
In this case only **event** column is being deleted.

I don’t think that `deleteColumn` accept an array of columns
> To permanently remove a column from the table deleteColumn function. This function takes any of the standard [column component look up](http://tabulator.info/docs/4.0/components#lookup) options as its first parameter.
So I think you have to send several messages.
