我下载了您的代码,找到问题原因是xlsx.full.min.js没有引入成功。您可以按照下列步骤改:
1.在根目录下新建static文件夹,将xlsx.full.min.js放入其中。

2.修改settings.py
增加

STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, "static"),
)

3.修改practice_budget.html

            <th>指导教师人数</th>
            <th>备注</th>
        </tr>
        {% for budget in budgets %}
        <tr>
            <td>[{{ budget.classID }}]{{ budget.name }}</td>
            <td>{{ budget.weeks }}</td>
            <td>{{ budget.mark }}</td>

        </tr>
        {% endfor %}
    </table>
    <button id="sheetjsexport"><b>Export as XLSX</b></button>

            let wb = XLSX.utils.table_to_book(document.getElementById("TableToExport"));
            /* Export to file (start a download) */
            XLSX.writeFile(wb, "SheetJSTable.xlsx");
        });
    </script>
