Dynamic Table in Mail Merge with different page for key attribute

[raushan316]

I have to prepare letter for students of different colleges. For each college, there should be one letter with name of all the students & their details in tabular format.
The students data is in excel is as below:
<style type="text/css"><!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--></style>

College Name	Student Name	Fathers Name	Address
ABC	XYZ	PQR	1, XYZ Street
PQR	ASJ	KDAJD	2, XYZ Street
ABC	SDA	DAD	1, XYZ Street
ABC	ADA	DADD	1, XYZ Street
PQR	RAR	EWQD	1, XYZ Street
PQR	AWRWQR	WRQR	1, XYZ Street

<colgroup><col style="width: 100px"><col width="100"><col width="100"><col width="100"></colgroup><tbody>
</tbody>

What I want is, separate letter for different colleges i.e. in this case, 2 letters should be printed : one letter having details of all students in ABC College, and another letter having details of PQR College.
The number of students in each college is not fixed, so the table should be dynamic in nature.
