How to use Vue and Excel to dynamically filter and sort data

How to use Vue and Excel to implement dynamic filtering and sorting of data

1. Introduction
Excel table is a powerful data processing tool, and Vue is a popular JavaScript framework for Build the user interface. In actual development, we may need to use Vue to dynamically filter and sort data in Excel tables. This article will introduce you to how to use Vue and Excel to dynamically filter and sort data.

2. Technical preparation
Before you start, make sure you have installed the following software:

1. Node.js and npm: used to install vue-cli and other dependencies.
2. Vue CLI: used to create and manage Vue projects.
3. pandas and openpyxl: used to process Excel files and data.

3. Create a Vue project
First, use the Vue CLI to create a new Vue project. Open the command line and execute the following command:

vue create dynamic-excel cd dynamic-excel

Then, select the default configuration to create the project.

4. Install the necessary dependencies
Next, install the required dependencies. Execute the following command in the command line:

npm install xlsx vuetify axios

The above command will install xlsx, used to process Excel files; vuetify, used to build a beautiful user interface; axios, used to make network requests.

5. Create components and styles
Create a folder named components in the src directory to store components. Create a file named ExcelTable.vue in the components folder to display Excel tables. Create a file named ExcelTable.scss under the styles folder for writing styles.

The ExcelTable.vue code is as follows:

ExcelTable.scss code is as follows:

@import "~vuetify/src/styles/styles.sass";

6. Use the ExcelTable component
Use the ExcelTable component in the App.vue file. The code is as follows:

7. Processing Excel files and data
Next, we will introduce how to process Excel files and data. Create a folder named utils in the src directory to store tool functions. Create a file named excel.js under the utils folder for processing Excel files and data.

excel.js code is as follows:

import XLSX from "xlsx"; export function readExcel(file) { return new Promise((resolve, reject) => { const reader = new FileReader(); reader.onload = e => { const data = new Uint8Array(e.target.result); const workbook = XLSX.read(data, { type: "array" }); const sheetName = workbook.SheetNames[0]; const worksheet = workbook.Sheets[sheetName]; const json = XLSX.utils.sheet_to_json(worksheet, { header: 1 }); resolve(json); }; reader.onerror = reject; reader.readAsArrayBuffer(file); }); }

8. Processing back-end data
According to the actual situation, you can use axios to obtain Excel files or data from the back-end and pass the data to ExcelTable components.

9. Compile and run
Execute the following commands in the command line to compile and run the project:

npm run serve

Open the browser and visit http://localhost:8080 to see to dynamically filter and sort Excel tables.

Summary
This article introduces how to use Vue and Excel to dynamically filter and sort data. By creating a Vue project, installing necessary dependencies, creating components and styles, and processing Excel files and data, a dynamically filtered and sorted Excel table was finally implemented. I hope this article will help you understand how to use Vue and Excel to dynamically filter and sort data.
