2 隐藏全选框

1. 通过修改样式不起作用

.el-table__header-wrapper .el-checkbox {
  visibility: hidden; // 不起作用
  display: none; // 不起作用
}

2. 动态添加样式

<el-table :header-cell-class-name="hideSelectAll">
  <el-table-column fixed type="selection" width="50" align="center" />
  <el-table-column label="客户名称" align="center" prop="clientName" />
  <el-table-column label="客户类型" align="center" prop="clientTypeName" />
  <el-table-column label="业务类型" align="center" prop="businessTypeName" />
  <el-table-column label="区域" align="center" prop="regionDetail" />
</el-table>
hideSelectAll({ row, cloumn, rowIndex, columnIndex }) {
  if (columnIndex === 0) {
    return "hideSelectAll";
  }
}
::v-deep {
    .hideSelectAll .cell {
       visibility: hidden;
    }
}

3 回显

回显数据要在el-table中添加两个属性

if (this.clients.length != 0) {
  this.clientTableData.forEach(row => {
    if (row.id == this.clients[0].id) {
      this.$refs.clientTableRef.toggleRowSelection(row, true);
    }
  })
}
