【.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 {
    position: absolute;
    background-color: #fff;
    display: none;
    box-sizing: border-box;
    overflow: hidden;
}

.fixed-table-header-columns .table,
.fixed-table-body-columns .table {
    border-right: 1px solid #ddd;
}

.fixed-table-header-columns .table.table-no-bordered,
.fixed-table-body-columns .table.table-no-bordered {
    border-right: 1px solid transparent;
}

.fixed-table-body-columns table {
    position: absolute;
    animation: none;
}

.bootstrap-table .table-hover > tbody > tr.hover > td{
    background-color: #f5f5f5;
}

?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：
