You can create a cell binding source, and then use the setBindingPath method to set the binding path for cell-level binding in a specified cell in the specified sheet area. Then set the data source for the sheet. For example:
You can use getBindingPath to get the binding path of cell-level binding from the specified cell in the specified sheet area.
