又get到一种思路，不光是layui。
外面这层table，就是用原生拼接的。
@Override
public List<Map<String, Object>> distribution(String begin,String end,String name,String hospitalCode) {
HashMap<String, Object> params = new HashMap<String, Object>();
StringBuffer buf = new StringBuffer();
List<HRateAllotDepartment> hRateAllotDepartment = rateAllotDepartmentDao.getRateDepartment(hospitalCode);
String str1 = "";
String str2 = "";
for(int i=0;i<hRateAllotDepartment.size();i++) {
str1 +=",sum(`"+hRateAllotDepartment.get(i).getDepartmentName()+"`)`"+hRateAllotDepartment.get(i).getDepartmentName()+"`";
str2 +=",max(case when e.`name`='"+hRateAllotDepartment.get(i).getDepartmentName()+"' then f.price else 0 end) `"+hRateAllotDepartment.get(i).getDepartmentName()+"`";
}
buf.append("select d.`name`,d.productId_,count(*) renshu,sum(price) total"+str1+" ");
buf.append(" from ( SELECT b.`name`,b.id productId_ ,d.id,max(b.price) price ");
buf.append(" "+str2+" FROM ");
buf.append(" dt_pay_health_order_product a "
+ "JOIN dt_pay_health_order d ON a.orderId = d.id "
+ "JOIN dt_pay_health_product b ON a.productId = b.id ");
buf.append(" JOIN dt_hospital_health_item c ON b.bizId = c.id "
+ "JOIN dt_hospital_health_order_use g ON g.orderProductId = a.id "
+ "JOIN dt_hospital_rate_allot f ON b.id = f.productId ");
buf.append(" JOIN dt_hospital_department e ON f.departmentId = e.id where g.createDate>=:begin and g.createDate<=:end and b.name like :name and a.state ='02' group by b.`id`,d.`id` ) d group by d.productId_ WITH ROLLUP ");
if(begin == null || begin.length() == 0){
begin = "1970-01-01";
}
if(end == null || end.length() == 0){
end = "2099-01-01";
}
params.put("begin",begin);
params.put("end",end);
params.put("name","%"+name+"%");
return this.getMapListByMap(buf.toString(), params);
}
可以看到，一开始是有一个list，这个list是医院医生可以配置的科室，这些科室就是动态的。这样一来后台即可得到动态数据。同理，如果在layui时用到page，在这里返回成page类型即可。接下来再看js
function toList(begin,end,name){
console.log(begin);
console.log(end);
$.ajax({
url: basePath + "/biz/hospital/rate/allot/list.do",
data: {
begin:begin,
end:end,
name:name
},
type : 'post',
dataType : 'json',
success : function(data) {
var arrayPrice = new Array();
for(var i=0;i<data.length;i++){
var arrayPrice1 = new Array();
for(var key in data[i]){
if(key!="name"&&key!="productId_"&&key!="renshu"&&key!="total"){
arrayPrice1[key]=data[i][key];
}
}
arrayPrice.push(arrayPrice1);
}
var title="";
var sumCols="";
var partCols=new Array();
for(var i=0;i<arrayPrice.length;i++){
var partColsStr = "";
for(var key in arrayPrice[i]){
if(i==0&&(arrayPrice[arrayPrice.length-1][key]!=0)){
title+="<th class='firstTh'>"+key+"（元）</th>";
}
if(i==(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){
sumCols+="<td class='secondTd'>"+arrayPrice[i][key]+"</td>";
}
if(i!=(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){
partColsStr += "<td class='thirdTd'>"+arrayPrice[i][key]+"</td>";
}
}
partCols.push(partColsStr);
}
var sRenshu = 0;
var stotal = 0;
var tablex = "";
tablex += "<tr class='firstTr'><th class='firstTh'>项目名称</th><th class='firstTh'>检查人数</th><th class='firstTh'>金额（元）</th>"+title+"</tr>";
if(data!=null && data.length>0){
for(var i=0;i<data.length-1;i++){
sRenshu+=data[i].renshu;
stotal+=data[i].total;
}
tablex += "<tr class='secondTr'><td class='secondTd'>总计</td><td class='secondTd'>"+sRenshu+"</td><td class='secondTd'>"+stotal+"</td>"+sumCols+"</tr>";
for(var i=0;i<data.length-1;i++){
{
tablex += "<tr class='thirdTr'><td class='thirdTd'>"+data[i].name+"</td>" +
"<td class='thirdTd'>" +
"<a style='color:#ff5722' href="+basePath +" rel="external nofollow" rel="external nofollow" /biz/hospital/rate/allot/toPageMx.do?startDate="+$("#startDate").val().toString()
+"&endDate="+$("#endDate").val().toString()
+"&productId_="+data[i].productId_+">"+
data[i].renshu+"</a></td>" +
"<td class='thirdTd'>"+data[i].total+ partCols[i] +
"</tr>";
}
}
}
$("#table_status").empty();
$("#table_status").append(tablex);
},
error : function() {
layer.msg('系统异常，请联系管理员!',{icon:2,time:2000});
}
});
}
可以在最上方图看到，有些字段是固定的，但是有些字段是动态的。思路是通过将调用接口返回出来的数据，动态的部分放到一个键值对数组下。这样一来，固定的部分，依然可以用返回的data得到，而动态的部分，用处理的数组循环赋值即可。动态表头就是动态数组的键。数据就是值。
function toList(begin,end,name){
console.log(begin);
console.log(end);
$.ajax({
url: basePath + "/biz/hospital/rate/allot/list.do",
data: {
begin:begin,
end:end,
name:name
},
type : 'post',
dataType : 'json',
success : function(data) {
var arrayPrice = new Array();
for(var i=0;i<data.length;i++){
var arrayPrice1 = new Array();
for(var key in data[i]){
if(key!="name"&&key!="productId_"&&key!="renshu"&&key!="total"){
arrayPrice1[key]=data[i][key];
}
}
arrayPrice.push(arrayPrice1);
}
var title="";
var sumCols="";
var partCols=new Array();
for(var i=0;i<arrayPrice.length;i++){
var partColsStr = "";
for(var key in arrayPrice[i]){
if(i==0&&(arrayPrice[arrayPrice.length-1][key]!=0)){
title+="<th class='firstTh'>"+key+"（元）</th>";
}
if(i==(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){
sumCols+="<td class='secondTd'>"+arrayPrice[i][key]+"</td>";
}
if(i!=(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){
partColsStr += "<td class='thirdTd'>"+arrayPrice[i][key]+"</td>";
}
}
partCols.push(partColsStr);
}
var sRenshu = 0;
var stotal = 0;
var tablex = "";
tablex += "<tr class='firstTr'><th class='firstTh'>项目名称</th><th class='firstTh'>检查人数</th><th class='firstTh'>金额（元）</th>"+title+"</tr>";
if(data!=null && data.length>0){
for(var i=0;i<data.length-1;i++){
sRenshu+=data[i].renshu;
stotal+=data[i].total;
}
tablex += "<tr class='secondTr'><td class='secondTd'>总计</td><td class='secondTd'>"+sRenshu+"</td><td class='secondTd'>"+stotal+"</td>"+sumCols+"</tr>";
for(var i=0;i<data.length-1;i++){
{
tablex += "<tr class='thirdTr'><td class='thirdTd'>"+data[i].name+"</td>" +
"<td class='thirdTd'>" +
"<a style='color:#ff5722' href="+basePath +" rel="external nofollow" rel="external nofollow" /biz/hospital/rate/allot/toPageMx.do?startDate="+$("#startDate").val().toString()
+"&endDate="+$("#endDate").val().toString()
+"&productId_="+data[i].productId_+">"+
data[i].renshu+"</a></td>" +
"<td class='thirdTd'>"+data[i].total+ partCols[i] +
"</tr>";
}
}
}
$("#table_status").empty();
$("#table_status").append(tablex);
},
error : function() {
layer.msg('系统异常，请联系管理员!',{icon:2,time:2000});
}
});
}
这块是name这些的是固定的，就排除掉，然后将数据放到arrayPrice1下再push到数组下。tablex就是表格的html。当时拼接的是分两步，先是表头，然后是数据。有个总计，后来在sql下加了WITH ROLLUP就得到了。
for(var key in arrayPrice[i]){
if(i==0&&(arrayPrice[arrayPrice.length-1][key]!=0)){
title+="<th class='firstTh'>"+key+"（元）</th>";
}
if(i==(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){
sumCols+="<td class='secondTd'>"+arrayPrice[i][key]+"</td>";
}
if(i!=(arrayPrice.length-1)&&(arrayPrice[arrayPrice.length-1][key]!=0)){
partColsStr += "<td class='thirdTd'>"+arrayPrice[i][key]+"</td>";
}
}这块就是动态的数据，title表头，sumCols总计，partColsStr具体数据，加到tablex下就行。
