你可以使用 showFooter 显示汇总行。 默认情况下，汇总行将显示为表格的最后一行。 你也可以使用 isFooterInserted 在数据中插入表格行。
你可以使用以下代码插入汇总行并显示下拉列表：
你还可以使用以下代码获取汇总行和下拉列表的是否可见：
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
function initSpread(spread) {
spread.suspendPaint();
var spreadNS = GC.Spread.Sheets;
var sheet = spread.getSheet(0);
var table = sheet.tables.add("table1", 0, 0, 5, 13, spreadNS.Tables.TableThemes.light1);
table.showFooter(true);
table.useFooterDropDownList(true);
sheet.setActiveCell(5, 4);
var dataArray = [
