grid中给单元格设置焦点可以调用grid的editCell (TD cell)

单元格进入编辑状态,受列上定义的editable属性和data的readonly规则影响

具体实现如下：

	Model.prototype.button10Click = function(event) {
		var data = this.comp("bizData1");
		var rowID = data.getCurrentRowID();
		var grid = this.comp("grid1");
		setTimeout(function() {
			grid.editCell(grid.getCell(rowID, "fSZ"));
		}, 5);
	};
