fields property
The fields that should be updated.
At least one field must be specified. The root tableColumnProperties is
implied and should not be specified. A single "*" can be used as
short-hand for listing every field. For example to update the column
width, set fields to "column_width". If '"column_width"' is included
in the field mask but the property is left unset, the column width will
default to 406,400 EMU (32 points).
