This article introduces how to use the el-table component to implement the table grouping, drag and drop sorting function in the Vue2 project. Suppose the table data is divided into two groups: "topped" and "non-topped", and the data in the group can be sorted by dragging, but cannot be dragged between groups.
Scene description
The project uses Vue2 and Element UI's el-table components. The table data is as follows:
- Top area: data number 1, 2, 3
- Non-topped area: data number 4, 5, 6
Target:
- The top area data (1, 2, 3) can be sorted from each other.
- Non-topped area data (4, 5, 6) can be sorted from each other.
- The data between the top and non-toping area (for example, 1 and 4) cannot be dragged and dropped from each other.
Implementation plan
Use vuedraggable
library to implement drag and drop function.
-
Install
vuedraggable
:npm install vuedraggable
-
Introducing
vuedraggable
:In Vue components:
import draggable from 'vuedraggable'
-
Data structure adjustment:
Divide the table data into two arrays:
data() { return { topData: [{ id: 1, content: 'top 1' }, { id: 2, content: 'top 2' }, { id: 3, content: 'top 3' }], normalData: [{ id: 4, content: 'normal 4' }, { id: 5, content: 'normal 5' }, { id: 6, content: 'normal 6' }] }; }, components: { draggable }
-
Use
vuedraggable
to implement drag and drop:In the template:
<template> <div> <h3>Top area</h3> <draggable group="top" v-model="topData"> <el-table :data="topData" style="width: 100%"> <el-table-column label="內(nèi)容" prop="content"></el-table-column> </el-table> </draggable> <h3>Non-topped area</h3> <draggable group="normal" v-model="normalData"> <el-table :data="normalData" style="width: 100%"> <el-table-column label="內(nèi)容" prop="content"></el-table-column> </el-table> </draggable> </div> </template>
-
Drag and drop end event processing:
In methods:
methods: { onEnd() { console.log('Top data:', this.topData); console.log('Non-subscribed data:', this.normalData); // Add data persistence or other update logic here} }
Through the above steps, the group drag and drop ordering of the el-table table can be realized, and the data between groups cannot be dragged and dropped. Remember to improve data persistence and other operations in actual applications as needed.

To develop a complete Python Web application, follow these steps: 1. Choose the appropriate framework, such as Django or Flask. 2. Integrate databases and use ORMs such as SQLAlchemy. 3. Design the front-end and use Vue or React. 4. Perform the test, use pytest or unittest. 5. Deploy applications, use Docker and platforms such as Heroku or AWS. Through these steps, powerful and efficient web applications can be built.

Single-page applications (SPAs) can be built using Laravel and Vue.js. 1) Define API routing and controller in Laravel to process data logic. 2) Create a componentized front-end in Vue.js to realize user interface and data interaction. 3) Configure CORS and use axios for data interaction. 4) Use VueRouter to implement routing management and improve user experience.

It is not recommended to directly modify the native code when separating WordPress front and back ends, and it is more suitable for "improved separation". Use the REST API to obtain data and build a user interface using the front-end framework. Identify which functions are called through the API, which are retained on the backend, and which can be cancelled. The Headless WordPress mode allows for a more thorough separation, but it is more cost-effective and difficult to develop. Pay attention to security and performance, optimize API response speed and cache, and optimize WordPress itself. Gradually migrate functions and use version control tools to manage code.

How to push video streams from Hikvision camera SDK to front-end Vue project? During the development process, you often encounter videos that need to be captured by the camera to be circulated...

The core of the front-end routing system is to map URLs to components. VueRouter and ReactRouter realize refresh-free page switching by listening for URL changes and loading corresponding components. The configuration methods include: 1. Nested routing, allowing the nested child components in the parent component; 2. Dynamic routing, loading different components according to URL parameters; 3. Route guard, performing logic such as permission checks before and after route switching.

The core differences between Vue.js and React in component development are: 1) Vue.js uses template syntax and option API, while React uses JSX and functional components; 2) Vue.js uses responsive systems, React uses immutable data and virtual DOM; 3) Vue.js provides multiple life cycle hooks, while React uses more useEffect hooks.

I'm having a headache when developing a project based on Laravel and Vue.js: How to create and manage forms efficiently. Especially when it is necessary to define the form structure on the backend and generate dynamic forms on the frontend, traditional methods appear cumbersome and error-prone. I tried many methods, but the results were not satisfactory. Finally, I discovered the k-eggermont/lara-vue-builder library, which not only simplified my workflow, but also greatly improved the development efficiency.
