Glossary Item Box

You can change the appearance of header cells by adding a color gradient. You can have a gradient from one color to another color.

You can implement a gradient appearance by creating a custom class which inherits existing cell classes (a general cell, in this case) and change the display to a gradient. You can also use the GradientHeaderRenderer class.

Using a Shortcut

Use the GradientHeaderRenderer class and the Renderer property for the column header row and row header column.


This example sets a gradient for the headers and the sheet corner.
