CellMaker Buttons (React)

The CellMaker class provides a simple way to create custom cells of common types within a FlexGrid.

This sample shows how to use the CellMaker class to create cells with buttons.

The CellMaker.makeButtons method allows you to specify both the text displayed in the button, as well as a handler for the button's click event.
