ODK XLSForms link the categorical codings to a variable type name in the 'survey' sheet. The codings are specified in the 'choices' sheet which has a `list_name` column that holds the variable type names. Each row that has that name will be associated with that categorical type coding. This function converts `coding` objects into tables that can be inserted into that 'choices' sheet. The categorical type is specified with the coding `.label`.
