vue结合element-ui table本地分页

<template>
  <el-table :data="tableData1.slice((start1-1)*length1,start1*length1)"
           height="300"
           style="width: 100%;text-align:center;margin-top:20px">
               <el-table-column prop="path" label="模块名称" sortable align="center">

               </el-table-column>
               <el-table-column prop="is_changed" label="是否修改" sortable align="center">

               </el-table-column>
           </el-table>
</template>

<script>
export default {
   data() {
      return {
          start1:1,
          length1:10,
          total1:0,
     }
  },
    methonds:{
       handleSizeChange1(val){
           this.start1=1
           this.length1=val
      },
      handleCurrentChange1(val){
          this.start1=val

      },
  }
}
//其实就是简单的数组截取
