Alain, suppose your {tabular} has 6 columns.
Then instead of starting the contents with  \hline
for the top row, use  \cline{2-6}  .
(That makes the "hole" in the top line for you.)

Now for that first cell use  \multicolumn{1}{...}{.....}
where the first {...} is the layout specifier for this cell.
e.g. if you had  |c|  for the column, now use  just  c| .
(Ergo, skip the first vertical line.)


For Jonathan the answer is similar to this latter trick.
He should use a complete row of \multicolumn{1}{...}{....}  cells.
e.g.

   \begin{tabular}{|c|c|c|c|c|}
   \multicolumn{1}{c}{Header 1}
   &\multicolumn{1}{c}{Header 2}
   &\multicolumn{1}{c}{Header 3}
   &\multicolumn{1}{c}{Header 4}
   &\multicolumn{1}{c}{Header 5}
   \\\hline
   ....2nd row ......
   \\\hline
   ....3rd row ......
   \\\hline
   etc.
   \\\hline
   \end{tabular}
