Ext grid合龙表头

Ext合并表头并不难，需要引入一个开源的扩展文件GroupHeaderPlugin.js和GroupHeaderPlugin.css

现在展示以前做过的一个小例子

var eventcolModel = new Ext.grid.ColumnModel({
	columns:[ 
	{
		header : '编号',
		dataIndex : 'id',
		hidden:true,
		editor : new Ext.grid.GridEditor(
		new Ext.form.TextField({
			allowBlank : false
		})
		)
	}, {
		header : '小时',
		dataIndex : 'startTimeHour',
		align:'right',
		width : 150,
		editor : new Ext.grid.GridEditor(
				startTimeHourCombo
		),
		renderer:function(value){//显示combo的text而不是显示value
		    return comboHourData[value][1];
		}
	}, 
	{
		header : '分钟',
		dataIndex : 'startTimeMin',
		align:'left',
		width : 150,
		editor : new Ext.grid.GridEditor(
				startTimeMinCombo
		),
		renderer:function(value){//显示combo的text而不是显示value
		    return comboMinData[value][1];
		}
	},  
	{
		header : '小时',
		dataIndex : 'endTimeHour',
		align:'right',
		width : 150,
		editor : new Ext.grid.GridEditor(
				endTimeHourCombo
		),
		renderer:function(value){//显示combo的text而不是显示value
		    return comboHourData[value][1];
		}
	}, 
	{
		header : '分钟',
		dataIndex : 'endTimeMin',
		align:'left',
		width : 150,
		editor : new Ext.grid.GridEditor(
				endTimeMinCombo
		),
		renderer:function(value){//显示combo的text而不是显示value
		    return comboMinData[value][1];
		}
	},
	{
		header : '亮度(%)',
		dataIndex : 'brightness',
		align:'center',
		width : 300,
		editor : new Ext.grid.GridEditor(
				brightnessCombo
		)/*,
		renderer:function(value){//显示combo的text而不是显示value
		    return comboBrightnessData[value][1];
	      }*/
	} ],//columns结束
	rows: [[
			{},
			{header: '开始时间', colspan: 2, align: 'center'},
			{header: '结束时间', colspan: 2, align: 'center'},
			{}
		]
	]
});

var eventGrid = new Ext.grid.EditorGridPanel({
		 id:'eventGird',
		 title:'event',
		 region:'center',
		 //height:200,
		 split:true,
	     store: eventStore,
	     cm:eventcolModel,
	     bbar:eventTb,
	     sm: new Ext.grid.RowSelectionModel({singleSelect:true}),
	     viewConfig:{
				forceFit:true
			},
		 plugins: [new Ext.ux.plugins.GroupHeaderGrid()]

	 });
