快速入门
ParamQuery Grid Pro是ParamQuery Grid的商业级版本，相对于之前研究的Bootstrap Table组件，就一字字稳，商业化的东西就是好，不会出一些莫名其妙的Bug,虽然网上资料不多但是官方文档非常详细（本次基于6.x版本，只是入门使用版本应该关系不大）
需要导入的文件
<link rel="stylesheet" href="../resources/css/pqbase/jquery-ui.css">
<link rel="stylesheet" href="../resources/css/pqbase/bootstrap.min.css">
<link rel="stylesheet" href="../resources/css/pqbase/pqgrid.min.css" >
<link rel="stylesheet" href="../resources/css/pqbase/pqgrid.ui.min.css" id="pqgrid_ui_link">
<link rel="stylesheet" href="../resources/css/pqbase/pqgrid.css" id="pqgrid_office_link">
<link rel="stylesheet" href="../resources/css/base/bootstrap.min.css">

<script src="../resources/js/pqbase/pq-localize-en.js"></script>
<script src="../resources/js/pqbase/jquery.resize.js"></script>
<script src="../resources/js/pqbase/bootstrap.min.js"></script>
这些文件我就不提供了，研究的话打开官网查看源代码，去扣下来就行了，官方也提供免费的评估版本（当然需要申请），使用的话就得去买一版了
你还有几张图片需要下载，不然你看不到表格上的一些按钮
这里随便找了一个官方例子
<div id="grid_json" style="margin:auto;"></div>
$(function () {
var data = [
{ rank: 1, company: 'Exxon Mobil', revenues: 339938.0, profits: 36130.0 },

{ rank: 5, company: 'General Motors', revenues: 192604.0, profits: -10567.0 },
{ rank: 6, company: 'Chevron', revenues: 189481.0, profits: 14099.0 },
{ rank: 7, company: 'DaimlerChrysler', revenues: 186106.3, profits: 3536.3 },

{ rank: 19, company: 'Crédit Agricole', revenues: 110764.6, profits: 7434.3 },
{ rank: 20, company: 'American Intl. Group', revenues: 108905.0, profits: 10477.0 }
];
var obj = {
width: "80%",
height: 400,
resizable: true,
title: "Grid From JSON",
showBottom: false,
scrollModel: { autoFit: true },
dataModel: { data: data }
};
$("#grid_json").pqGrid(obj);
});
导入上方的js文件，在Html中写一个div,r然后在js中将表格渲染进该div中
能够正确显示出表格你就成功了
表格构建（官网Remote paging(远程分页)例子）
HTML
<div id="grid_paging" style="margin:5px auto;"></div>
js
$(function () {
var colM = [ //列定义，pqgrid会根据dataIndex自动填充数据
{ title: "Order ID", width: 100, dataIndx: "OrderID" },
{ title: "Customer Name", width: 130, dataIndx: "CustomerName" },
{ title: "Product Name", width: 190, dataIndx: "ProductName" },
{ title: "Unit Price", width: 100, dataIndx: "UnitPrice", align: "right" },
{ title: "Quantity", width: 100, dataIndx: "Quantity", align: "right" },
{ title: "Order Date", width: 100, dataIndx: "OrderDate", dataType:'date', align:'right' },
{ title: "Required Date", width: 100, dataIndx: "RequiredDate", dataType:'date' },
{ title: "Shipped Date", width: 100, dataIndx: "ShippedDate", dataType:'date' },
{ title: "ShipCountry", width: 100, dataIndx: "ShipCountry" },
{ title: "Freight", width: 100, align: "right", dataIndx: "Freight" },
{ title: "Shipping Name", width: 120, dataIndx: "ShipName" },
{ title: "Shipping Address", width: 180, dataIndx: "ShipAddress" },
{ title: "Shipping City", width: 100, dataIndx: "ShipCity" },
{ title: "Shipping Region", width: 110, dataIndx: "ShipRegion" },
{ title: "Shipping Postal Code", width: 130, dataIndx: "ShipPostalCode" }
];
var dataModel = { //数据源
location: "remote", //数据位置远程
dataType: "JSON", //数据格式JSON
method: "GET", //获取方法GET
url: "/pro/invoice/paging", //获取地址
getData: function (dataJSON) { //返回后的分页处理，需要前后台协调
var data = dataJSON.data;
return { curPage: dataJSON.curPage, totalRecords: dataJSON.totalRecords, data: data };
}
};
var grid1 = $("div#grid_paging").pqGrid({ //表格属性的创建与定义
width: 800, height: 450, //宽高
dataModel: dataModel, //数据模型，上面定义
colModel: colM, //表格，列的定义
freezeCols: 2, //固定列，固定的列数
pageModel: { type: "remote", rPP: 20, strRpp: "{0}" }, //默认的页码与大小
sortable: false,
selectionModel: { swipe: false }, //选定方式
wrap: false, hwrap: false,
numberCell: { resizable: true, width: 30, title: "#" },
title: "Shipping Orders",
resizable: true //列宽可调整大小
});
});
java 官方是为了可以方便演示，你的数据接口不用和他一样只需要注意返回值和参数就行
package controller;
import domain.Invoice;
import flexjson.JSONSerializer;
import flexjson.transformer.DateTransformer;
import java.util.Date;
import java.util.List;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.support.JdbcDaoSupport;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
/**
* @author paramvir
*/
@Controller
public class InvoiceController extends JdbcDaoSupport{
@RequestMapping(value="/invoice/paging",method=RequestMethod.GET)
public @ResponseBody String paging(@RequestParam int pq_curpage, @RequestParam int pq_rpp)
{
int total_Records = getJdbcTemplate().queryForInt(
"Select count(*) as count from invoices order by orderID " );
int skip = (pq_rpp * (pq_curpage - 1));
if (skip >= total_Records)
{
pq_curpage = (int)Math.ceil(((double)total_Records) / pq_rpp);
skip = (pq_rpp * (pq_curpage - 1));
}
List<Invoice> invoices = getJdbcTemplate().
query("Select * from invoices order by orderID limit " + skip + " , " + pq_rpp,
new BeanPropertyRowMapper(Invoice.class));
JSONSerializer serializer = new JSONSerializer().exclude("*.class");
String serializedInvoices = serializer
.transform(new DateTransformer("MM/dd/yyyy"), Date.class)
.serialize(invoices);
String sb = "{\"totalRecords\":" + total_Records + ",\"curPage\":" + pq_curpage + ",\"data\":" + serializedInvoices + "}";
return sb;
}
}
API简单介绍
pqgrid的demo给的非常全面，几乎不用你自己费力气去构建，直接copy就差不多满足你的需求，而且pqgrid还会提供相应的后台代码
demo地址：https://paramquery.com/pro/demos
API地址：https://paramquery.com/pro/api
主要研究功能介绍
诸如列固定，列可拖动，后台分页等在PQGrid中都非常稳定 唯一缺陷就是没有Cookie Paging功能，如果想实现修改后返回原来页面需要自己编写
后台分页
该功能在表格构建中已经讲解
查询功能 我使用官方文档中的传值方式不太方便，而且把查询条件输入框加入到表格内部也不太美观
function Search(){
url="/BootStrapTableTest/test/selectall2.do"; //我的url设置为了全局变量，方便修改
var params = $('#_searchForm').serializeObject();//将form中的查询条件转换成对象
//传入数据
DM = $grid.pqGrid("option", "dataModel");
DM.postData = params;
pm = $grid.pqGrid("option", "pageModel");
//刷新表格重新获取数据
refresh();
}
//刷新按钮
function refresh() {
$grid.pqGrid("refreshDataAndView");
}
