Overview

SpreadJS supports built-in context menus, the context menu can be opened by right-clicking on the SpreadJS instance. The contents of this menu depend on which area of the workbook is clicked.

The context menu provides the following abilities: Theme is the same as the current spread theme. Change the filter context menu data result. Modify the menu view's appearance and structure. You can use the spread.options.allowContextMenu option to control whether to show the built-in context menu or not.
