使用element ui -el-table方式编写

功能点：点击全选/单选可以进行删除

  <el-table
            :data="date"
            ref="grayscaleTableRef"
            min-height="288"
            max-height="510"
            style="width: 100%"
            header-row-class-name="tableHeader"
            :header-cell-style="{
              background: '#F0F2F5',
              fontFamily: 'PingFangSC-Regular',
              fontWeight: '400',
              color: '#222D38',
            }"
            @selection-change="checked1"
            :row-class-name="rowClassName"
