[MiKTeX] margins of a page containing landscape table

[Fangyin Z. <fz...@en...>]

Miktex friends, 

I am writing a document which contains some pages with landscape long tables, but the whole document is in portrait. 

I set the margins of the document as I require, and these margins look correct in pages in portrait, but for the pages with landscape table, the margins are totally wrong. How can I correct these landscape table margins? 

Thanks a lot for any help!
