导出到反应表中的 CSV 按钮

Question

寻找一种方法将“导出到 CSV”按钮添加到作为 npmjs 包的反应表（ https://www.npmjs.com/package/react-table ）。

我需要添加一个自定义按钮以将表格数据导出到 csv 或 xls 格式的 excel 工作表？

下面是集成的样子：

 import React from "react";
import "react-dropdown/style.css";
import "react-table/react-table.css";
import ReactTable from "react-table";
import { CSVLink } from "react-csv";

const columns = [
  {
    Header: "name",
    accessor: "name", // String-based value accessors!
  },
  {
    Header: "age",
    accessor: "age",
  },
];

class AllPostPage extends React.Component {
  constructor(props) {
    super(props);
    this.download = this.download.bind(this);
    this.state = {
      tableproperties: {
        allData: [
          { name: "ramesh", age: "12" },
          { name: "bill", age: "13" },
          { name: "arun", age: "9" },
          { name: "kathy", age: "21" },
        ],
      },
      dataToDownload: [],
    };
  }

  download(event) {
    const currentRecords = this.reactTable.getResolvedState().sortedData;
    var data_to_download = [];
    for (var index = 0; index < currentRecords.length; index++) {
      let record_to_download = {};
      for (var colIndex = 0; colIndex < columns.length; colIndex++) {
        record_to_download[columns[colIndex].Header] =
          currentRecords[index][columns[colIndex].accessor];
      }
      data_to_download.push(record_to_download);
    }
    this.setState({ dataToDownload: data_to_download }, () => {
      // click the CSVLink component to trigger the CSV download
      this.csvLink.link.click();
    });
  }

  render() {
    return (
      <div>
        <div>
          <button onClick={this.download}>Download</button>
        </div>
        <div>
          <CSVLink
            data={this.state.dataToDownload}
            filename="data.csv"
            className="hidden"
            ref={(r) => (this.csvLink = r)}
            target="_blank"
          />
        </div>
        <div>
          <ReactTable
            ref={(r) => (this.reactTable = r)}
            data={this.state.tableproperties.allData}
            columns={columns}
            filterable
            defaultFilterMethod={(filter, row) =>
              String(row[filter.id])
                .toLowerCase()
                .includes(filter.value.toLowerCase())
            }
          />
        </div>
      </div>
    );
  }
}

export default AllPostPage;

这也适用于过滤器。

看看这个 npm 库 - https://www.npmjs.com/package/react-csv

例如 -

 import {CSVLink, CSVDownload} from 'react-csv';

const csvData =[
  ['firstname', 'lastname', 'email'] ,
  ['John', 'Doe' , '[e-mail]'] ,
  ['Jane', 'Doe' , '[e-mail]']
];
<CSVLink data={csvData} >Download me</CSVLink>
// or
<CSVDownload data={csvData} target="_blank" />
