Stacker tables give you the option to change field names and types within the app.
Edit field names and types
Click Manage fields and data
Hover over the field you want to edit
Click the downward arrow
Edit field name
Select another field type from the dropdown menu
Only some field type conversions can happen without losing data. For example, you can convert a string field to a long text field with no loss of data. Converting a number to a long text will clear the data in the field.
Go to Manage fields and data
Hover over the field you want to delete
Click downward arrow
Click delete button
You can delete all Stacker Table fields, other than the primary field.
