1. 冻结（X-1）列
2. 冻结（Y-1）行
如果想冻结前三行，也就是不想冻结列。按照上面的说法，选择A4单元格（X=A,Y=4)冻结后就是前三行。
可以的，实现方法如下：(function ($) {
'use strict'
$.extend($.fn.bootstrapTable.defaults, {
fixedColumns: false,
fixedNumber: 1

bootstrap-table-fixed-columns.js修改后的源码
.fixed-table-container thead th .th-inner, .fixed-table-container tbody td .th-inner {
line-height: 18px
}
.fixed-table-pagination .pagination a {
padding: 5px 10px
}
.fixed-table-toolbar .bars, .fixed-table-toolbar .search, .fixed-table-toolbar .columns {
margin-top: 5px
margin-bottom: 5px
}
bootstrap-table-fixed-columns.css修改后
主要修改的地方：
1）源码里面将thead和tbody分别封装成了一个单独的表格，修改后将thead和tbody放到了一个table里面；
2）依次遍历冻结的列放入到固定的tbody里面；
