【.net core】yisha框架，bootstrap-table组件增加固定列功能
需要引入
bootstrap-table-fixed-columns.css和bootstrap-table-fixed-columns.js文件
文件代码：
bootstrap-table-fixed-columns.css样式文件代码
.fixed-table-header-columns,
.fixed-table-body-columns {

样式及脚本存放路径
项目bundleconfig.json文件修改内容为图片中红框标记内容
yisha-jquery-bootstrap-table-plugin.js脚本文件修改内容，在红框标记的方法内增加标记参数
视图shard文件中引入：
页面调用：
