我一直在努力解决这个问题，试图让它正常工作。我有一组复杂的长表，我想让它正确显示。
我想要做的是将目录编在一起。我的做法是，如果有些组共享同一张图片，我只想在第一个表格上方显示图片，前提是这些组出现在同一页上。如果表格跨越到下一页，或者如果有另一个组共享同一张图片，然后出现在下一页上，我希望它再次显示在顶部组的正上方。
我正在使用 PHP 生成 tex 代码，它会检查各组是否使用相同的图像，如果满足这些参数，则不会显示该图像。除了第 1 种情况外，我在其他所有情况下都能正常工作，第 1 种情况是，当具有相同图像的新组被推到新页面时，因为新页面不适合。我不知道如何“以编程方式”检测它现在在新页面上，因此需要显示图像。我正在尝试使用 AddEverypageHook 设置一个标志，它可以工作，但必须在生成表格后设置它，因为图像反而会出现在后面的表格中。这很有意义，因为我怀疑它首先生成表格，确定它需要新页面并推入它，然后设置标志（这意味着它在插入图像所需的点之后设置了标志）。我有一些代码可以生成一个 PDF，显示我正在尝试做的事情。
在此示例中，所有产品组都共享同一张图片，因此应显示图片的唯一表格应该是每页的第一个表格。但情况并非总是如此。如果另一个组使用不同的图片，它将显示在具有新图片的新组上方（继续在同一页面上），因此显示的图片并不总是顶部图片。生成后（可能需要运行几次才能正确生成所有数据），如果您查看第 4 页，您会注意到它没有显示在第一个组上方，但显示在第二个组上方。

如果您注意到，第一组有 1 张图像，但下一组有另一张跨越多页的图像，下一组也是如此，因此变得非常复杂。
