We got away from the Multiple table scheme, because we had a hard time
lining up the columns of the multiple tables.  So we simply use a single
table, with parent child tags, and when the user collapse/expand a parent
item, we loop through the table and hide/show the child items.

Here is the code.  What we do is pass the table id and row number to
collapse/expand to the toggle function.

function ToggleChildren(TableID,RowNum,bExpand)
{
   var MyTable = document.getElementById(TableID);

   ParentRow = MyTable.rows[RowNum];

   var ParentID = ParentRow.getAttribute("id");

   //Get selected row
   for (var i = RowNum+1; i < MyTable.rows.length;i++)
   {
      MyRow = MyTable.rows[i];
      var PID = MyRow.getAttribute("pid");
      if (PID == ParentID)
      {
         if (bExpand == 'true')
         {
            MyRow.style.display = "";
         }
         else
         {
            MyRow.style.display = "none";
         }
         var AlreadyExpanded = MyRow.getAttribute("expanded");
         if (bExpand == 'true' && AlreadyExpanded == 'true')
         {
            ToggleChildren(TableID,i,bExpand);
         }
         else if (bExpand == 'false')
         {
            ToggleChildren(TableID,i,bExpand);
         }
      }
   }
}

function Toggle(TableID,RowNum)
{
   //Get only one table for now
   var MyTable = document.getElementById(TableID);

   ParentRow = MyTable.rows[RowNum];

   var Expanded = ParentRow.getAttribute("expanded");

   if (Expanded == 'true')
   {
      Expanded = 'false';
   }
   else
   {
      Expanded = 'true';
   }

   //Set expanded flag to accordingly
   ParentRow.setAttribute("expanded",Expanded);

   ToggleChildren(TableID,RowNum,Expanded);

}
