你好大卫，

根据我对你的帖子的理解。似乎你的问题有两个部分。

Based on my understanding of your post. Seems you issue has two parts.

第一部分是子报表导致新页面没有tablix的列标题。嗯，这是设计的。正常的解决方法是使用页眉而不是列标题。

The 1st part is that the subreport caused new page doesn't have the column header of the tablix. Well, this is by design. The normal work around is to use page header instead of column header.

第二部分是我们希望页眉文本框对应页面内容。由于页眉不属于分组，这可能是导致设计中不同步的原因。我建议你尝试在
此主题。这可能对您的问题有所帮助。

The 2nd part is that we want the page header text boxes correspond to the page content. Since the page header don't belong to the grouping, this may be the reason cause the un-sync in your design. I suggest you try using Global Page Name method that mentioned in this thread. This could be helpful for your issue.

祝您好运，

Lukas
