Description

How can I create a custom tool that merges the selected cells in the KendoReact Spreadsheet?

Solution

This can be achieved by adding a custom button, MergeCellsButton, to the tools array in the toolbar prop of the Spreadsheet. Inside the MergeCellsButton, use the Spreadsheet's ref to access the active sheet, retrieve the selected cells with the selection method, and then merge them using the merge method.
