vue中使用computed搜索解决分页后进行搜索出现页数错误的现象（getSearchInfo）

<template>
  <div>
    <!-- 基于el-table二次封装的一个table组件，功能包括：搜索、编辑、删除、分页 -->
    <el-table
      :data="
        getSearchInfo.slice(
          (currpage - 1) * Data.pageSize,
          currpage * Data.pageSize
        )
      "
      style="width: 100%"
    >
      <template v-for="(item, index) in Data.tableTitle">
        <el-table-column
          :prop="item.prop"
          :label="item.label"
          align="center"
          :key="index"
          :formatter="formatData"
        >
        </el-table-column>
      </template>
      <el-table-column align="center" v-if="Data.showEditAndDelete">
