vue的表格和分页

前面有提到在vue里面，对于表格的使用：vue2.0 + element-ui 实战项目-渲染表格（四）https://www.jianshu.com/p/fea8cacc04b9，在实战的过程中，往往还要选择一个合适的分页，搭配着一起使用，尤其是数据比较多的时候，必然会做出分页效果。

关于一些经常用到的参考文档：这里都罗列一下,查找起来比较方便

1：在组件里面找一个自己比较喜欢的分页的样式
https://element.eleme.cn/#/zh-CN/component/pagination

其实我们可以看到，文档里面的样式非常的简单
复制一下这段代码

<el-pagination
  background
  layout="prev, pager, next"
  :total="1000">
</el-pagination>

就可以在页面上看到一个静态的分页的效果了

2：最重要的一个步骤就是点击分页的办法

  // 初始页currentPage、初始每页数据数pagesize和数据data
    handleSizeChange: function (size) {
      this.pagesize = size;
      console.log(this.pagesize); //每页下拉显示数据
    },
    handleCurrentChange: function (currentPage) {
      this.currentPage = currentPage;
      console.log(this.currentPage); //点击第几页
    },

3：对表格中获取到的json数据进行处理

:data="pvData.slice((currentPage - 1) * pagesize, currentPage * pagesize)"

4:将前面的静态分页也进行修改一下，加上方法和变量

 <el-pagination
      style="margin: 12px 0px"
      background
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page="currentPage"
      :page-sizes="[5, 10, 20, 40]"
      :page-size="pagesize"
      layout="total, sizes, prev, pager, next, jumper"
      :total="pvData.length"
    >
    </el-pagination>

5：写一个完整的实例：

json

{"msg":"success","total":0,"code":1,"data":[{"id":6,"userOrganId":null,"userName":"super","sex":1,"realName":"super","birthday":null,"password":"202cb962ac59075b964b07152d234b70","roleId":1,"roleName":"角色1","organId":1,"organName":"部门1","authority":0,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1},{"id":13,"userOrganId":null,"userName":"super2","sex":1,"realName":"super","birthday":null,"password":"202cb962ac59075b964b07152d234b70","roleId":1,"roleName":"角色1","organId":1,"organName":"部门1","authority":0,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1},{"id":14,"userOrganId":null,"userName":"999","sex":1,"realName":"999","birthday":null,"password":"d41d8cd98f00b204e9800998ecf8427e","roleId":1,"roleName":"1","organId":1,"organName":"1","authority":1,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1},{"id":27,"userOrganId":null,"userName":"21","sex":null,"realName":"21","birthday":null,"password":"d41d8cd98f00b204e9800998ecf8427e","roleId":1,"roleName":"","organId":1,"organName":"","authority":1,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1},{"id":28,"userOrganId":null,"userName":"111","sex":1,"realName":"111","birthday":null,"password":"202cb962ac59075b964b07152d234b70","roleId":1,"roleName":"1","organId":1,"organName":"14","authority":1,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1},{"id":29,"userOrganId":null,"userName":"212","sex":0,"realName":"121","birthday":null,"password":"d41d8cd98f00b204e9800998ecf8427e","roleId":1,"roleName":"1","organId":1,"organName":"13","authority":1,"companyId":1,"phone":null,"organIds":null,"isPagination":false,"page":1,"rows":1}]}

实例代码

<template>
  <div class="tab-container">
    <el-table
      :data="pvData.slice((currentPage - 1) * pagesize, currentPage * pagesize)"
      border
      fit
      highlight-current-row
      style="width: 100%"
    >
      <el-table-column
        prop="userName"
        label="用户名"
        width="180"
      ></el-table-column>

      <el-table-column prop="realName" label="姓名"></el-table-column>
      <el-table-column prop="sex" label="性别"  :formatter="formatSex"></el-table-column>
      <el-table-column prop="organName" label="所属部门"></el-table-column>
      <el-table-column prop="authority" label="权限"></el-table-column>
      <el-table-column prop="roleName" label="角色"></el-table-column>
      
    </el-table>

    <el-pagination
      style="margin: 12px 0px"
      background
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page="currentPage"
      :page-sizes="[5, 10, 20, 40]"
      :page-size="pagesize"
      layout="total, sizes, prev, pager, next, jumper"
      :total="pvData.length"
    >
    </el-pagination>
  

  </div>
</template>
<script>
//调用接口
import {getQuerycheckList} from "@/api/permission/user";

export default {
  data() {
    return {
      // 分页
      currentPage: 1, //初始页
      pagesize: 5, //    每页的数据
      total: 0,
      pvData: [],
      
    };
  },

  created() {
    this.getQuerycheckList();
  },
  methods: {
    // 初始页currentPage、初始每页数据数pagesize和数据data
    handleSizeChange: function (size) {
      this.pagesize = size;
      console.log(this.pagesize); //每页下拉显示数据
    },
    handleCurrentChange: function (currentPage) {
      this.currentPage = currentPage;
      console.log(this.currentPage); //点击第几页
    },

    //查询题目列表信息接口
    getQuerycheckList() {
      const params = {
        organId: 1,
        userOrganId: 1,
        authority: 0,
        page: 1,
        rows: 5,
        isPagination: false,
      };
      getQuerycheckList(params).then((res) => {
        console.log("查询题目列表信息", res);
        this.pvData = res.data;
      });
    },
    //格式化性别
    formatSex(row, column) {
    return row.sex === 1? "男" : "女";
    }
  },
};
</script>
<style scoped>
.tab-container {
  margin: 30px;
}
</style>

效果：
