电子表格添加菜单

通常，你需要从 onOpen 函数调用 addMenu，以便在加载电子表格时自动创建菜单。

 // The onOpen function is executed automatically every time a Spreadsheet is loaded
 function onOpen() {
   var activeSheet = SpreadsheetApp.getActiveSpreadsheet();
   var menuItems = [];
   // When the user clicks on "addMenuExample" then "Menu 1", the function Myfunction1 is executed.
   menuItems.push({name: "Menu 1", functionName: "Myfunction1"});
   menuItems.push(null); // adding line separator
   menuItems.push({name: "Menu 2", functionName: "Myfunction2"});

   activeSheet.addMenu("addMenuExample", menuEntries);
 }
