grid

参考示例：合并单元格

调用方法：margeCells。如下代码：

grid.on("load", onLoad);
function onLoad(e) {
    var grid = e.sender;

    var marges = [
        { rowIndex: 1, columnIndex: 0, rowSpan: 1, colSpan: 2 },
        { rowIndex: 3, columnIndex: 0, rowSpan: 4, colSpan: 3 }
    ];

    grid.margeCells(marges);
}
