.Box {display: flex;justify-content: center;align-items: center;
}::v-deep.el-table .disableSelection .cell .el-checkbox__inner {display: none;position: relative;

</style>
效果图
关键代码总结
// 在要修改的那一列加render-header属性
<el-table-column label="姓名" prop="name" :render-header="(h, obj) => renderHeader(h, obj, '你的参数')"</el-table-column>
// methods中写方法
renderHeader (h, { column, $index }, type) {// console.log('列表加载就会触发', h, { column, $index }, type)console.log(column.label);let that = this// 逻辑是 h() 括号里包裹标签 第一个参数是标签名 第二个是属性 第三个是标签内容 如果是多个标签需要包裹数组return h('div', [// 列名称// h('span', column.label),// 按钮h('el-button', {props: {type: 'primary',size: 'small',},style: 'color:#fff;',// class: "{ active: showSelectMore }",// class: 'className',on: {// 各种事件触发click: function () {that.clickButton(type)}}}, '姓名')],)},
