这是我第一次使用数据表，插件有一些问题。首先，除了它不喜欢对 Date 列或只有 1 个字符的“Success”列进行排序之外，它的所有工作都很好。对于其余的列，它将毫无问题地排序。我正在使用分页并一次加载 10 行。
这是我的 HTML：

除了最后两个之外，我可以对所有列进行排序。我设置了它，所以它在加载时按日期 desc 排序，但如果我尝试再次对其进行排序，我会长时间看到“处理”屏幕并且它永远不会完成。我不确定为什么只是这两个字段导致问题。我试过设置索引，但没有帮助。SQL 语句在 Management Studio 中运行没有问题，所以我不知道实际问题可能是什么。有没有人有什么建议？谢谢
