I am writing a two column IEEE paper (standard IEETran). I want to create a table that spans multiple pages in LaTeX. I have tried longtable and that breaks pages rightly. However the problem is my table is also very wide. I can't fix it in the middle of the page. The table moves into and after the right margin. Is there any way that I can move the left side of my table a little bit towards left, so that my whole table is centered according to its total width not from a fixed position.
