How to reduce space between tr?

I am trying to replicate a page I have been given, and I have nearly finish, but I have a small problem with it.

The space between tr are too big. I have done it reducing the margin top and bottom but there is a point where rows overlap.

Does anybody have any suggestions?

e.g.

<style type="text/css">
.divContainer
{   
margin:10px;
background-color:#C7D8EE;
border:2px solid #0076BF;
text-align:left;    
}

.tableContainer
{
color:#0076BF;
margin: -10px 0px -10px 0px;
border-spacing: 10px;
empty-cells:show;
width:90%;

}   
.tableContainer tr td{
 white-space:nowrap;
}

.tableContainerRow2{
background-color:white;
border:2px solid #0076BF;

}
</style>
  <div class="divContainer">
      <table class="tableContainer" cellspacing="10px">
          <tr>
              <td>NHS Number</td>
              <td>&#160;</td>

              <td rowspan="2" style="font-weight:bold;vertical-align:middle;">Tick when<br/> care starts</td>

Remove cellspacing="10px" from the <table> and use CSS only. You already have definied it with border-spacing: 10px;.
