Start new column when readdir moves to new dir

Original Issue:

I am using readdir to snag file names from multiple directories. I was wondering if there is a way to arrange the data so that each time it starts a new directory it makes a new column i.e.

---| user1  | user2  | user3  |
---| file1a | file2a | file3a |
---| file1b | file2b | file3b |
---| file1c | file2c | file3c |
---| file1d |   ^    | file3d |
---| file1e |   |    |   ^    |
---|    ^   |  end   |   |    |
---|    |   |  dir2  |  end   |
---|   end  | #start |  dir3  |
---|   dir1 |  col3  |  etc.  |
---| #start |        |        |
---|  col2  |        |        |

if this is possible that would be great; as far as displaying the user names across the top I have that part down already. I just need to know if the columns part can be done and if so how to do it.

The coding that I have so far is:

            echo "$entry\n";

            foreach($target_folders as $target_item){

                if ((substr($target_item, 0, 1) == '.'))
                        continue;
                echo '<tr>';
                echo '<td>';        
                echo $target_item;
                echo '</td>';
                echo '</tr>';
                                    }
                            }
