loop in horizontal direction (php-html)

Hey, I've been wondering. I know it's possible to make a php loop that each time generates a new <tr>. In that case the results are stored under eachother. Now I want to know if I can do the same in a horizontal direction. The result should be something like this, I loop through available projects: Project1 Project2 Project3 Project4 ... 1 45 89 5 8 2 23 9 65 31 3 23 91 55 73 4 11 90 82 38 The first column is fixed, but I have an unkown amount of projects Hope this aint to much html related. Thanks in advance, Reinhart Viane
