可以使用 find, findByName，或者 all 获取表格实例。例如：
可以使用 move 方法来改变表格的位置。以及使用 resize方法调整表格的大小。例如：
如果你不再需要表格了，可以使用 remove 方法来移除它。例如：
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
function initSpread(spread) {
spread.suspendPaint();
