代码:

<el-table
        ref="myTable"
        v-loading="crud.loading"
        :row-key="getRowKey"
        :header-cell-style="{ color: '#FFF', background: '#333' }"
        :cell-style="{ color: '#FFF', background: '#333' }"
        :data="
          crud.data.slice((currentPage - 1) * pageSize, currentPage * pageSize)
        "
        style="width: 100%"
        @selection-change="selectionChange"
        :default-sort="{ prop: 'posName', order: '' }"
        @sort-change="sortChange"
      >

 <el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page.sync="currentPage"
      :page-size="pageSize"
      layout="total, prev, pager, next,sizes"
      :total="crud.data.length"
    >
    </el-pagination>

`data中定义:

 currentPage: 1, //当前页
 pageSize: 10, //每页显示条数

方法代码

 handleSizeChange(pageSize) {
      this.pageSize = pageSize;
    },
    // 页码改变切换
    handleCurrentChange(currentPage) {
      this.currentPage = currentPage;
    },
