创建自己的jquery表格插件
时间：2015-11-26 15:28作者：fang人气：132
在模仿easyui的dataGrid表格插件的同时，自己去封装了一个。实现了基本的json数据的动态加载，自动分页，全选全不选，鼠标悬浮变色，隔行变色等
由于涉及到ajax访问，所以必须部署到iis上才能看出效果，先给大家看一下效果图：
css样式
/* CSS Document */
body {
font: 14px/1.43 "Helvetica Neue", Tahoma, "Microsoft YaHei", Arial;
color: #253443;
margin: 0 auto;
padding: 0 auto;

table {
border-collapse: collapse;
border-spacing: 0;
background: #FFF;
font-size: 12px;
width: 100%;
border: 1;
width: 100%;
}
thead {
display: table-header-group;
vertical-align: middle;
border-color: inherit;
}
tr {
display: table-row;
vertical-align: inherit;
border-color: inherit;
}
table thead tr {
background-color: #E6F0FF;
}
table thead tr th {
padding: 5px 8px;
font-weight: normal;
color: #999;
border-bottom: 1px solid #B50802;
vertical-align: bottom;
line-height: 20px;
}
tbody {
display: table-row-group;
vertical-align: middle;
border-color: inherit;
}
table tbody tr td {
padding: 8px;
border-top: 0px;
border-bottom: 1px solid #DDD;
vertical-align: middle;
line-height: 20px;
}
table tfoot tr td {

background-color: #F4F4F4;
height: 20px;
padding: 8px 0px;

}
table tfoot tr td input {

}
table tfoot tr td span {
display: inline-block;
cursor: pointer;
height:20px;
padding:0 10px;

}
.mouseover {

本文只是为大家提供了一个框架、思路，如何将这些知识点串连在一起，还需要大家认真的学习研究，动手创建一个属于自己的jquery表格插件。
