使用 bindingPath 方法来绑定表格到数据记录, 然后绑定表格的列到数据记录的数据字段。 例如：
当您设置其他数据源时，该表格将自动绑定到相应的记录。
我们还提供了一种简单的方法 bind API以解决复杂的调用问题，您可以通过以下代码使用它，例如：
绑定数据源时，更改数据源后可以得到脏数据项：
var spreadNS = GC.Spread.Sheets;
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
function initSpread(spread) {
//define BindingPathCellType
function BindingPathCellType() {
spreadNS.CellTypes.Text.call(this);
}
BindingPathCellType.prototype = new spreadNS.CellTypes.Text();
BindingPathCellType.prototype.paint = function (ctx, value, x, y, w, h, style, context) {
if (value === null || value === undefined) {
var sheet = context.sheet, row = context.row, col = context.col;
if (sheet && (row === 0 || !!row) && (col === 0 || !!col)) {
var bindingPath = sheet.getBindingPath(context.row, context.col);
if (bindingPath) {
value = "[" + bindingPath + "]";
}
}
}
spreadNS.CellTypes.Text.prototype.paint.apply(this, arguments);
};
