[TheOOnewbie]

while using this code string[,] elements = new string[3, 5];

        elements[0, 0] = "Pizza";
        elements[0, 1] = "Pane";
        elements[0, 2] = "Spaghetti";
        elements[0, 3] = "Spaghetti";
        elements[0, 4] = "Spaghetti";

        elements[1, 0] = "1";
        elements[1, 1] = "2";
        elements[1, 2] = "3";

        elements[2, 0] = "4";
        elements[2, 1] = "5";
        elements[2, 2] = "6";

        lt.Add(new LatexTable(elements));

it fails and says (! Extra alignment tab has been changed to \cr.
