fields property
The fields that should be updated.
At least one field must be specified. The root tableCellProperties is
implied and should not be specified. A single "*" can be used as
short-hand for listing every field. For example to update the table cell
background solid fill color, set fields to
"tableCellBackgroundFill.solidFill.color". To reset a property to its
default value, include its field name in the field mask but leave the
field itself unset.
