the problem is the way you have your table layout ... you should go for a 3-column instead of the 4-column that you have

this is how you have your table:

     HEADER
---------------
|--|---|---|--|
|--|---|---|--|
|--|-------|--|
|--|-------|--|
---------------

it should be:

     HEADER
---------------
|--|-------|--|
|--|-------|--|
|--|-------|--|
|--|-------|--|
---------------

if you do, your problem will be solved
