vue+Element做表格的批量增加

全部代码如下：

<template>
  <div>
    <el-button @click="addAll">批量增加</el-button>
    <el-table :data="tabledatas" border>
      <el-table-column label="title" align="center">
        <template slot-scope="scope">
          <span>{{scope.row.title}}</span>
        </template>
      </el-table-column>
      <el-table-column label="text" align="center">
        <template slot-scope="scope">
          <span>{{scope.row.text}}</span>
        </template>
      </el-table-column>
    </el-table>
    <el-dialog
      title="添加数据"
      @close="addDialogClose"
      :visible.sync="dialogTableVisible"
      :close-on-click-modal="false"
    >
      <!-- 添加用户的表单 -->
      <el-form ref="addData" :rules="rulesAddData" :model="addData" label-width="80px">
        <el-form-item prop="title" label="标题">
          <el-input v-model="addData.title"></el-input>
        </el-form-item>
        <el-form-item prop="text" label="内容">
          <el-input v-model="addData.text"></el-input>
        </el-form-item>
        <el-form-item>
          <el-button @click="dialogTableVisible = false">取消</el-button>
          <el-button type="primary" @click="submit">确定</el-button>
        </el-form-item>
      </el-form>
    </el-dialog>
  </div>
</template>
<script>
export default {
  data() {
    return {
      tabledatas: [],
      dialogTableVisible: false, // 添加用户弹框
      // 添加数据

      }
    };
  },

  methods: {
    // 关闭弹框的回调
    addDialogClose() {
      this.$refs.addData.resetFields(); // 清空表单
    },

    submit() {
      let _this = this;
      _this.$refs["addData"].validate(valid => {
        if (valid) {
          let data = _this.addData.title.split("-");
          let data0 = data[0];
          let tit = data0.replace(/[0-9]/gi, "");
          let num0 = data0.replace(/[^0-9]/gi, "");
          let num = data0.replace(/[^0-9]/gi, "");
          for (let i = 0; i < data[1] - num0 + 1; i++) {

            let obj = {};
            obj.title = tit + aa;
            obj.text = _this.addData.text;
            _this.tabledatas.push(obj)
          }
          _this.$message({
            message: "添加成功",
            type: "success",
            duration: 1000
          });
          _this.dialogTableVisible = false;
        } else {
          return;
        }
      });
    },

    //批量新增
    addAll() {
      let _this = this;
      _this.dialogTableVisible = true;
    }
