在我们开发PC端的项目使用表单时,尤其是crm系统,应该经常会遇到这样的需求, 用户需要根据设置来自定义显示列。 查了element的官方文档, 并没有此类组件, 所以手动封装了一个简单的组件, 希望能在大家开发此类需求时能够有所帮助。
具体效果图如下:
自定义显示列 (可实现拖拽进行排序,点击选中,再次点击取消选中)
按照用户已设置好的字段排序/显示/隐藏每一列
首先实现拖拽排序的话我们需要借助一个插件:
npm install Vuedraggable -S
具体的组件代码如下, 代码内已写有详细的注释,在这里就不过多赘述了。。
setTable.vue
<template>
<div>
<el-dialog title="自定义显示列" :visible.sync="dialogVisible" width="50%">
<div class="select-menus menus-box">
<p class="menus-title">拖动区块调整显示顺序</p>
<div class="menus-content">
<draggable v-model="selected" @update="datadragEnd" :options="{animation:500}">
<transition-group>
<div v-for="menu in selected" :key="menu.field" class="drag-item item">{{menu.name}}</div>
</transition-group>
</draggable>
</div>
</div>
<div class="menus-container menus-box" v-if="fields.length">
<p class="menus-title">选择显示列</p>
<div class="menus-content">
<div
class="item"
:class="{active:menu.active}"
v-for="menu of fields"
:key="menu.field"
@click="onSelect(menu)"
>{{menu.name}}</div>
</div>
</div>
<span slot="footer" class="dialog-footer">
<el-button @click="dialogVisible = false">取 消</el-button>
<el-button type="primary" @click="onSave">确 定</el-button>

在这里其实也可以设置成固定的列宽或者通过服务器返回具体的尺寸, 这样的话就不用写这么多的if语句了, 会更加方便简洁..
其实刚接到这个需求时,感觉挺复杂的, 尤其是需要进行拖动, 还要根据服务器返回不同的字段来进行表单列的排序。 但整体做下来并没有我想象的那么麻烦。 大家在遇到需求时, 也一定不要一直想的太多, 一定要先去尝试, 说不定它并没有你想的那么难..
到此这篇关于vue自定义表格列的文章就介绍到这了,更多相关vue自定义表格列内容请搜索编程网以前的文章或继续浏览下面的相关文章希望大家以后多多支持编程网!
