生成的 excel 中出现的额外行

Question

我正在使用 npm 包xlsx生成在表中有表的 excel 报告。一切正常，除了您可以在附加的屏幕截图中看到第 10 行与下面的所有表格相同。我确定我犯了一个 html 表错误，但两个小时后无法弄清楚错误究竟是什么。我附上了截图和html。

import React from 'react';

const Report = ({ data }) => {
  // console.log(data);
  return (
    <table>
      <tbody>

          <td>SOme cool report</td>
        </tr>
        <tr>
          <td>Report Name:</td>
          <td colSpan='6'>
            02 Dummy
          </td>
        </tr>
        <tr />

Answer 1

嵌套表格 HTML 结构导致整个表格创建额外的行。

从您的代码中删除此行 - 这应该删除添加到 Excel 工作表中的额外行。

    <table>
      <tbody>
        <tr>

从你的代码。

请在此处查看更正后的代码（由于不支持的方法，您无法在代码和框上运行它 - 但代码可在本地设置上运行）

https://codesandbox.io/s/extrarowexcelsheet-333cv?file=/src/App.js

import React from "react";
import XLSX from "xlsx";
import { useRef } from "react";


const Report = () => {
  // Data is just placeholder
  const [data, setData] = React.useState([["Hello"], ["Bye"]]);
  const myContainer = useRef(null);

  const exportFile = () => {
  
    const ws = XLSX.utils.table_to_sheet(myContainer.current);
    const wb = XLSX.utils.book_new();
    XLSX.utils.book_append_sheet(wb, ws, "SheetJS");
    /* generate XLSX file and send to client */
    XLSX.writeFile(wb, "sheetjs.xlsx");
  };

  return (
    <div>
      <h2> This is Demo for StackOverFlow Issue #68269850</h2>
      <p> Extra row appearing in generated excel </p>
      <button
        style={{ backgroundColor: "#4CAF50", padding: "10px" }}
        onClick={exportFile}
      >

      </button>
