<div dir="ltr">Hello Heba<br><br>As Alan already said, longtable is not yet ready for RTL. I have tried several attempts to figure out how I can do RTL tables with longtable but so far I have failed. For instance, recently I asked this question <a href="http://tug.org/pipermail/texhax/2011-September/018083.html">http://tug.org/pipermail/texhax/2011-September/018083.html</a><br>
<br>You only can hope that I add support for longtable in bidi package if I find a working answer/solution to my question/problem. <br><br>It is true that I am an expert on RTL typesetting but after all, I am still a human and can not do/solve everything just myself.<br>
