How to implement multi-condition filtering of table data through Vue and Excel

As the data continues to increase, we often need to perform multi-condition filtering in the table to quickly locate the data that meets our needs. With the help of Vue and Excel, we can easily implement this functionality.

First, we need to introduce the Excel file into Vue and convert it into an operable data format. This can be achieved by using the papaparse library. The following is a code example for importing and converting Excel files:

<template>
  <div>
    <input type="file" @change="handleFileUpload" />
    <table>
      <tr v-for="(row, index) in filteredData" :key="index">
        <td v-for="(cell, cellIndex) in row" :key="cellIndex">
          {{ cell }}
        </td>
      </tr>
    </table>
  </div>
</template>

<script>
import { parse } from "papaparse";

export default {
  data() {
    return {
      fileData: [],
      filteredData: []
    };
  },
  methods: {
    handleFileUpload(e) {
      const file = e.target.files[0];
      parse(file, {
        complete: (results) => {
          this.fileData = results.data;
          this.filterData();
        }
      });
    },
    filterData() {
      // Add your filtering logic here
      // You can use this.fileData to access the original data
      // Set the filtered data to this.filteredData
    }
  }
};
</script>

In the above code, we use the parse method in the papaparse library to convert the uploaded Excel file Is an array fileData containing tabular data. By using the @change event to monitor the file upload action, we can obtain the uploaded file in time and perform analysis and conversion. Please note that we also define a filteredData array to store data filtered according to filter conditions.

Next, we need to implement the filtering logic. You can customize the filtering conditions as needed and store the filtered data in the filteredData array. The following is a simple example that demonstrates how to filter table data based on entered keywords:

<template>
  <div>
    <input type="file" @change="handleFileUpload" />
    <input type="text" v-model="searchKeyword" placeholder="请输入关键词" />
    <button @click="filterData">搜索</button>
    <table>
      <tr v-for="(row, index) in filteredData" :key="index">
        <td v-for="(cell, cellIndex) in row" :key="cellIndex">
          {{ cell }}
        </td>
      </tr>
    </table>
  </div>
</template>

<script>
import { parse } from "papaparse";

export default {
  data() {
    return {
      fileData: [],
      filteredData: [],
      searchKeyword: ""
    };
  },
  methods: {
    handleFileUpload(e) {
      const file = e.target.files[0];
      parse(file, {
        complete: (results) => {
          this.fileData = results.data;
          this.filterData();
        }
      });
    },
    filterData() {
      if (!this.searchKeyword) {
        this.filteredData = this.fileData;
        return;
      }
      this.filteredData = this.fileData.filter((row) => {
        return row.some((cell) => {
          return cell.toString().toLowerCase().includes(this.searchKeyword.toLowerCase());
        });
      });
    }
  }
};
</script>

In the above example, we added a text box for entering keywords, and clicked "Search" "Filtering logic is triggered after the button. The filterData method filters the table data and stores the data that meets the filtering conditions in the filteredData array. Here we use the filter method and the some method to implement fuzzy matching filtering.

Through the above sample code, we can easily implement the multi-condition filtering function of table data. You can customize the filtering logic according to your own needs, such as using date range, value size, multiple keywords, etc. By combining with Vue, we can quickly and flexibly filter and display data on the front-end page, improving our work efficiency.

I hope this article can provide some help for you to implement multi-condition filtering of table data. I wish you every success with Vue and Excel!
