添加表格有两种方式。第一种方式是使用 add 添加一个空的表格，示例代码如下：
第二种方式就是使用 addFromDataSource 创建一个带数据源的表格。例如：
使用这两种方式都能够完成对表格的初始化。
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
function initSpread(spread) {
var spreadNS = GC.Spread.Sheets;
var sheet = spread.getSheet(0);
var source = [

];
spread.suspendPaint();
var table = sheet.tables.addFromDataSource("Table1", 2, 1, source, spreadNS.Tables.TableThemes.medium7);
table.showFooter(true);
table.showHeader(true);
table.highlightFirstColumn(true);
table.highlightLastColumn(false);
table.setColumnFormula(2, "=SUBTOTAL(109,[Credit])");
table.setColumnFormula(3, "=SUBTOTAL(109,[Score])");
table.setColumnValue(0, "Total");
sheet.setColumnWidth(0, 20);
sheet.setColumnWidth(1, 130);
sheet.setColumnWidth(2, 70);
sheet.setColumnWidth(3, 70);
sheet.setColumnWidth(4, 70);
sheet.setColumnWidth(5, 100);
spread.resumePaint();
