项目中要实现表格多表头，结合网上的例子自己实现了一个，包含frozenColumns情况。
一，通过标签创建
效果：
<table id="schoolGrid" class="easyui-datagrid" style="100%;height:100%;padding:5px;" url="data/datagrid_data.json" singleSelect="true" rownumbers="true"> <thead> <tr> <th rowspan="3" colspan="4" align="center" field="QKQQRY" width="320">缺课缺勤人员</th> <th colspan="8" align="center" field="QKQQQKTJ" width="870">缺课缺勤情况统计</th> </tr> <tr> <th colspan="2" field="BGZT" align="center" width="120" align="center">报告状态</th> <th colspan="2" field="QKTS" align="center" width="120" align="center">缺课天数</th> <th colspan="4" field="QKQQYY" align="center" width="240">缺课缺勤原因</th> </tr> <tr> <th rowspan="2" field="SRQK" width="80" align="center">首日缺课</th> <th rowspan="2" field="LXQK" width="80" align="center">连续缺课</th> <th rowspan="2" field="SW" width="80">上午</th> <th rowspan="2" field="XW" width="80" align="center">下午</th> <th colspan="3" field="YZZ" width="80" align="center">因症状</th> <th field="YZZ2" width="80" align="center">原症状</th> </tr> <tr> <th field="XM" width="80" align="center">姓名</th> <th field="XB" width="80" align="center">性别</th> <th field="NL" width="80">年龄</th> <th field="NJBJ" width="120" align="center">年级班级（部门）</th> <th field="FR" width="80" align="center">发热</th> <th field="FRDS" width="80">发热度数</th> <th field="ZYZZJMS" width="240" align="center">主要症状及描述</th> <th field="CRB" width="120" align="center">传染病</th> </tr> </thead> </table>
二，使用Javascript创建
效果同上；
html:
<table id="schoolGrid" style="margin:10px;"></table>
js:
$('#schoolGrid').datagrid({
fit:true,
striped:true,
collapsible:true,
method:'get',
url:'',
fitColumns:false,
remoteSort:false,
pagination:true,
rownumbers:false,
showFooter:false,
singleSelect:true,
data:[
{"XM":"马菲菲","XB":"女","NL":18,"NJBJ":"一年级",
"SRQK":"无","LXQK":"无","SW1":"是","XW":"否",
"FR":"是","FRDS":"36.50","ZYZZJMS":"头疼脑热心跳加速","CRB":"无"}
],
columns:[[
{field:'QKQQRY',rowspan:3,colspan:4,title:'缺课缺勤人员',420,align:'center'},
{field:'QKQQQKTJ',colspan:8,title:'缺课缺勤情况统计',870,align:'center'}
],[
{field:'BGZT',colspan:2,title:'报告状态',120,align:'center'},
{field:'QKTS',colspan:2,title:'缺课天数',120,align:'center'},
{field:'QKQQYY',colspan:4,title:'缺课缺勤原因',240,align:'center'}
],[
{field:'SRQK',rowspan:2,title:'首日缺课',80,align:'center'},
{field:'LXQK',rowspan:2,title:'连续缺课',80,align:'center'},
{field:'SW1',rowspan:2,title:'上午',80,align:'center'},
{field:'XW',rowspan:2,title:'下午',80,align:'center'},
{field:'YZZ',colspan:3,title:'因症状',80,align:'center'},
{field:'YZZ2',title:'原症状',80,align:'center'}
],[
{field:'XM',title:'姓名',100,align:'center'},
{field:'XB',title:'性别',80,align:'center'},
{field:'NL',title:'年龄',80,align:'center'},
{field:'NJBJ',title:'年级班级（部门）',140,align:'center'},
{field:'FR',title:'发热',80,align:'center'},
{field:'FRDS',title:'发热度数',80,align:'center'},
{field:'ZYZZJMS',title:'主要症状及描述',340,align:'center'},
{field:'CRB',title:'传染病',140,align:'center'}
]]
});
附：
有固定列效果：
js:
$('#schoolGrid').datagrid({
fit:true,
striped:true,
collapsible:true,
method:'get',
url:'',
fitColumns:false,
remoteSort:false,
pagination:true,
rownumbers:false,
showFooter:false,
singleSelect:true,
data:[
{"XM":"马菲菲","XB":"女","NL":18,"NJBJ":"一年级",
"SRQK":"无","LXQK":"无","SW1":"是","XW":"否",
"FR":"是","FRDS":"36.50","ZYZZJMS":"头疼脑热心跳加速","CRB":"无"}
],
frozenColumns:[[
{field:'QKQQRY',rowspan:3,colspan:4,title:'缺课缺勤人员',420,align:'center'}
],[
],[
],[
{field:'XM',title:'姓名',100,align:'center'},
{field:'XB',title:'性别',80,align:'center'},
{field:'NL',title:'年龄',80,align:'center'},
{field:'NJBJ',title:'年级班级（部门）',140,align:'center'}
]],
columns:[[
{field:'QKQQQKTJ',colspan:8,title:'缺课缺勤情况统计',870,align:'center'}
],[
{field:'BGZT',colspan:2,title:'报告状态',120,align:'center'},
{field:'QKTS',colspan:2,title:'缺课天数',120,align:'center'},
{field:'QKQQYY',colspan:4,title:'缺课缺勤原因',240,align:'center'}
],[
{field:'SRQK',rowspan:2,title:'首日缺课',80,align:'center'},
{field:'LXQK',rowspan:2,title:'连续缺课',80,align:'center'},
{field:'SW1',rowspan:2,title:'上午',80,align:'center'},
{field:'XW',rowspan:2,title:'下午',80,align:'center'},
{field:'YZZ',colspan:3,title:'因症状',80,align:'center'},
{field:'YZZ2',title:'原症状',80,align:'center'}
],[
{field:'FR',title:'发热',80,align:'center'},
{field:'FRDS',title:'发热度数',80,align:'center'},
{field:'ZYZZJMS',title:'主要症状及描述',340,align:'center'},
{field:'CRB',title:'传染病',140,align:'center'}
]]
});
