书在桌子上用英语可以说成 "The book is on the table." 这个短语来源于拉丁语中的 "Liber est in mensa"，意思是 "书在桌子上"。

一些英文例句可以是：

Please put the book on the table.

The book is on the table, where it belongs.

I left my book on the table, so it should still be there.

Have you seen the book that was on the table? It's not there anymore.
