el-table表格单选

el-radio是要传给后端的字段名

 <el-table :data="tableData" class="table" ref="table" 
          height="485px" :row-key="(row) => row.id" @row-click="rowClick">
          <el-table-column label="选择" width="55" align="center">
            <template slot-scope="scope">
              <el-radio :label="scope.row.num" v-model="tableRadio">{{ '' }}
              </el-radio>
            </template>
          </el-table-column>
 </el-table>

 data() {
    return {
      tableData: [],
      tableRadio: "",
    };
  },

val.xxx赋值为需要传给后端的字段名

    // 选择项目 单选样式
    rowClick(val) {
      this.tableRadio = val.num
;
    },

隐藏调radio label的显示

   .el-radio__label {
      display: none;
    }

回显：

      this.tableRadio = xxx; //直接赋值
