Blank lines showing up in a display

I'm having a problem with a display.  I'm getting a small white lines in between these rows.

<tr>
      <td height = "157.5" bgcolor = "DCF7DC" style= "text-align:right" font color= "blue" class="Body_Labels">
            <a href = "Space_Display.php?id=NY10500005101001">Joe Fresh / portion of GR VACANT</a>
      </td>

      <td rowspan = "1" bgcolor = "ffbbff" style = "text-align:center" class="Body_Labels"> 510
      </td>
</tr>

<tr>
      <td height = "70" bgcolor = "F6F7D7" style= "text-align:right" font color= "blue" class="Body_Labels">
            <a href = "Tenant_Display.php?id=NY10500005001004">GNC</a>
      </td>

      <td rowspan = "3" bgcolor = "ffbbff" style = "text-align:center" class="Body_Labels"> 500
      </td>
</tr>

<tr>
      <td height = "35" bgcolor = "DCF7DC" style= "text-align:right" font color= "blue" class="Body_Labels">
            <a href = "Tenant_Display.php?id=NY10500005001003">Building Entrance</a>
      </td>
</tr>

<tr>
      <td height = "87.5" bgcolor = "F6F7D7" style= "text-align:right" font color= "blue" class="Body_Labels">
            <a href = "Tenant_Display.php?id=NY10500005001001">Zara</a>
      </td>
</tr>                                 

</table>

I can't see where it's coming from
