When a column's lookup is an array in the data source schema, a combo box cell type is set to the column.
This is the sample code of lookup array.
When the lookup is a relationship name, a multi-column list will be set to the column after the View data is fetched.
This is the sample code of lookup string.
When the lookup is an option which contains a relationship name and some columns options, a multi-column list with specified columns will be set to the column.
This is the sample code of lookup options.
