说明：电子表格，点击保存按钮，触发宏事件，如下图所示；
创建客户端onRenderReport事件宏，如下：
function main(spreadsheetReport) {
var that = spreadsheetReport.spreadsheetReportWriteBack;
that.__new_doSaveClick = function() {
windowAlert("电子表格点击保存按钮触发宏事件!");
this.doSaveClick();
}
that.removeListener(that.elem_btnSave, "click", that.doSaveClick, that);
that.addListener(that.elem_btnSave, "click", that.__new_doSaveClick, that);
}
