reactjs - 反应表选择行没有正确创建复选框

Question

我是 REACT 新手，无法让表格组件正常工作。我在这里react-tables使用包和教程示例，但我在组件文件中执行所有操作并将其添加到我的. 基本上，我正在尝试创建一个带有分页、排序和带有复选框的可选行的表。我的问题是我只能在标题中填充复选框（见下文）。 table.jsApp.js

这是我的代码；我在这里做错了什么？注意 - 我的行是使用页面而不是行创建的，并且来自我的 API。对于如何解决这个问题，有任何的建议吗？

Answer 1

从. <td {...cell.getCellProps()}>{cell.render('Cell')}</td>_tr

这应该有效：

<tbody {...getTableBodyProps()}>
  {page.map((row, i) => {
    prepareRow(row);
    return (
      <tr {...row.getRowProps()}>
        {row.cells.map((cell) => {
          return (
            <td {...cell.getCellProps()}>{cell.render("Cell")}</td> // fix return statement
          );
        })}
      </tr>
    );
  })}
</tbody>
