headerColorStyle property
The color of the first row or column.
If this field is set, the first row or column is filled with this color and the colors alternate between first_band_color and second_band_color starting from the second row or column. Otherwise, the first row or column is filled with first_band_color and the colors proceed to alternate as they normally would. If header_color is also set, this field takes precedence.
Implementation
ColorStyle? headerColorStyle;
