GridBase.defaultStyles are the default styles about all cells of the grid area. In other words, if do not specify a separate style in each area, it will be displayed according to the value specified in defaultStyles. In addition, the property, which has not been specified separately in defaultStyles, will follow the default style set specified within the grid.

Revert to the default font.
Make the text color as red. ("Product name" column will not follow since it has already been set as blue.)
Revert to the default text color.
