【问题描述】：
第 1 部分
我让我的数据表与 obj 迭代一起工作，但我正在移动到 DRF-datatables.. 虽然我让示例站点运行没有问题，但我的实际实现却让我很头疼。基本上，我整个周末都在展示一个似乎正在加载数据的表格（因为分页显示了正确的信息）但我的行都是空白的：https://i.imgur.com/ImA23Zo.png
然后我尝试在脚本中添加“列”部分，这打破了整个表格：https://i.imgur.com/ykwf58P.png
如果我将 ajax 调用更改为
"ajax": "/api/entry/?format=datatables",
然后我得到最紧密的工作表：https://i.imgur.com/p5G5uzk.png - 但是问题仍然是行是空的，如果我添加列，那么一切都会中断。
我哪里错了？我也没有收到任何错误消息，因此很难调试数据表。
可能是第 2 部分..
我什至需要使用 DRF 数据表吗？我的最终目标是能够选择多行，然后编辑所有这些条目的交易。
最终目标示例
- 选择 3 笔交易
- 点击表格顶部某处的下拉菜单
- 从该下拉列表中选择交易PK
- 点击保存
- 表格显示最新数据
