Draw lines within a table (repeating group)

Question

I have a table of 6X6 (rowsxcolumns) built using Word 2010. The cells starting from 2nd row to 5th row are merged and another table is created in this place with a repeating group. This means, the no. of rows this 2nd table would have is dynamic (based on the results)
Because of the layout requirement, I need vertical lines drawn for each of the columns in table 1 but excluding Row 1 and Row 6 (these are sort of headers). Is there a way to achieve this?
I tried using "Draw Shapes" and inserting vertical lines in the positions I want. But since this shape is of constant length and 2nd table contains dynamic rows, it isn't working if it has fewer/greater no. of rows.
Any ideas would be highly appreciated.
Thanks!

Ok,
I will assume that you have a dataVector that contains Vectors that have a String and an Integer in it. You pass this dataVector to the following method, that returns a Vector which contains the same data grouped. I assume also that your dataVector is sorted before:
public Vector groupVector(Vector dataVector) {
Vector r;
Vector v = new Vector(2,2);
if (dataVector.size()==0) return null; // no data there - return null
String name = (String) ((Vector) dataVector.elementAt(0)).elementAt(0);
int sum = 0;
for (int i = 0; i<dataVector.size();i++)
{ String curname = (String) ((Vector) dataVector.elementAt(i)).elementAt(0);
if (name.equals(curname))
{ sum += ((Integer) ((Vector) dataVector.elementAt(i)).elementAt(1)).intValue(); }
else
{ r = new Vector(2);
r.add(name);
r.add(new Integer(sum));
v.add(r);
name = curname;
sum = ((Integer) ((Vector) dataVector.elementAt(i)).elementAt(1)).intValue();
} // end else
} // end for-loop
r = new Vector(2);
r.add(name);
r.add(new Integer(sum));
v.add(r);
return v;
} // end of methodI have not tested it nor compiled - leave that to you
Hope this helps
