你可以通过使用 bind 方法来将表格绑定到有记录的字段，将表列绑定到数据的字段。当你设置数据源时，表格将会自动地绑定到对应的记录。
例如：
SpreadJS 提供了绑定API来解决复杂的需求，你可以参考如下代码：
示例 1:
示例 2:
如果已经绑定了数据源，你可以获取到被修改过的数据行：
var spreadNS = GC.Spread.Sheets;
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
function initSpread(spread) {
var sheet = spread.getActiveSheet();
var spreadNS = GC.Spread.Sheets;
var data = {
name: 'Jones', region: 'East',
sales: [
{orderDate: '1/6/2013', item: 'Pencil', units: 95, cost: 1.99, isDelivered: true},
{orderDate: '4/1/2013', item: 'Binder', units: 60, cost: 4.99, isDelivered: false},
{orderDate: '6/8/2013', item: 'Pen Set', units: 16, cost: 15.99, isDelivered: false}
]
};
var convert = function (item) {
return item['cost'] + '$';
}
var table = sheet.tables.add('tableSales', 0, 0, 5, 5);
table.style(spreadNS.Tables.TableThemes["medium4"]);
var tableColumn1 = new spreadNS.Tables.TableColumn(1, "orderDate", "Order Date", "yyyy-mm-dd");
var tableColumn2 = new spreadNS.Tables.TableColumn(2, "item", "Item");
var tableColumn3 = new spreadNS.Tables.TableColumn(3, "units", "Units");
var tableColumn4 = new spreadNS.Tables.TableColumn(4, "cost", "Cost", null, null, convert);
var tableColumn5 = new spreadNS.Tables.TableColumn(5, "isDelivered", "Delivered", null, new GC.Spread.Sheets.CellTypes.CheckBox());
table.autoGenerateColumns(false);
table.bind([tableColumn1, tableColumn2, tableColumn3, tableColumn4, tableColumn5], 'sales', data);
sheet.setColumnWidth(0, 120);
sheet.setColumnWidth(1, 120);
sheet.setColumnWidth(2, 120);
sheet.setColumnWidth(3, 120);
sheet.setColumnWidth(4, 120);
document.getElementById("getState").addEventListener('click',function () {
var table = sheet.tables.findByName("tableSales");
if (table) {
var dataArr = table.getDirtyRows();
var str = "";
for (var i = 0; i < dataArr.length; i ++) {
str += dataArr[i].row + ", ";
}
document.getElementById("stateText").value = str;
}
});
}
