问题描述
我需要你的帮助，
我似乎不明白为什么表中的第一行（ABC-123-123456）消失或出现一旦顶部列被固定就被隐藏。因为我的工作使用IE7，我还需要能够有一个浏览器兼容的粘性列标题。
I can't seem to figure out as to why the first row in the table (ABC-123-123456) disappears or appears to be hidden once the top columns are fixed. As my work uses IE7 still I need to be able to have a browser compliant sticky column headers.
