      :model="ruleForm"
      ref="ruleForm"
      label-width="100px"

      <el-table :data="ruleForm.tableList" style="width: 100%">
        <el-table-column prop="name">
          <!-- 变量rules -->
          <template slot-scope="scope">
            <el-form-item
              label="活动名称"
              :prop="'tableList.' + scope.$index + '.name'"
              :rules="rules.name"
            >
              <el-input v-model="scope.row.name"></el-input>
            </el-form-item>
          </template>
        </el-table-column>
        <el-table-column prop="region">
          <!-- 行内rules -->
          <template slot-scope="scope">
            <el-form-item
              label="活动区域"
              :prop="'tableList.' + scope.$index + '.region'"
              :rules="[{ required: true }]"
            >
              <el-select v-model="scope.row.region" placeholder="活动区域">
                <el-option label="区域一" value="shanghai"></el-option>
                <el-option label="区域二" value="beijing"></el-option>
              </el-select>
            </el-form-item>
          </template>
        </el-table-column>
      </el-table>
    </el-form>
    <div style="margin-top: 20px">
      <el-button type="primary" @click="submitForm('ruleForm')">提交</el-button>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      ruleForm: {
        tableList: []
      },
      rules: {
        name: [
          { required: true, message: "请输入活动名称", trigger: "blur" },
          { min: 3, max: 5, message: "长度在 3 到 5 个字符", trigger: "blur" }
        ]
      }
    };
  },
  methods: {
    addItem() {
      this.ruleForm.tableList.push({
        name: "",
        region: ""
      });
    },

    submitForm(formName) {
      this.$refs[formName].validate((valid) => {
        if (valid) {
          alert("submit!");
        } else {
          console.log("error submit!!");
          return false;
        }
      });
    }
  }
};
</script>

<style rel="stylesheet/scss" lang="scss">
.rataMdel {
  .el-table td {
    padding: 6px 0;
  }
  .el-form-item__error {
    display: none;
  }
  .header-flex {
    display: flex;
    align-items: center;
    justify-content: space-between;
  }
  .tableTitle {
    font-size: 20px;
    margin-bottom: 30px;
  }
  .charts-box {
    width: 100%;
    display: flex;
    justify-content: center;
  }
  .tableText {
    padding: 15px;
    font-size: 15px;
    color: #333333;
  }
  .small-num {
    display: inline-block;
    width: 70px;
  }
  .small-string {
    display: inline-block;
    width: 130px;
  }
  p {
    margin: 0;
    padding: 0;
  }
  .el-form-item {
    display: inline-block;
    margin-bottom: 0px;
  }
}
</style>

关键代码:

 :prop="'tableList.' + scope.$index + '.name'"

注意点:

删除数据时,注意验证规则
