Help! How can I split table with 3 masterdata

I have a long table it does not fit to width of page so I split it 3 pieces and use 3 groupheader and 3 masterdata like below.

Page1 group is according to the first city
*****************************************
GroupHeader1 (first city name - Table1)
Masterdata1 (Table1)(First piece of the Table1)
GroupHeader2(first city name - Tablo1)
Masterdata2 (Table1)(Second piece of the Table1)
GroupHeader3(first city name - Tablo1)
Masterdata3 (Table1)(Third piece of the Table1)
**************************************************
Page2 group is according to the second city
*****************************************
GroupHeader1 (secondcity name - Table1)
Masterdata1 (Table1)(First piece of the Table1)
GroupHeader2(second city name - Tablo1)
Masterdata2 (Table1)(Second piece of the Table1)
GroupHeader3(secondcity name - Tablo1)
Masterdata3 (Table1)(Third piece of the Table1)
**************************************************
Above is the desired report but not like this. The result is below;


Page1 group is according to the first city
*******************************************************
GroupHeader1 (first city name - Table1)
Masterdata1 (Table1)(First piece of the Table1)
***************************************************
Page2 group is according to the second city
*************************************************
GroupHeader1 (first city name - Table1)
Masterdata1 (Table1)(First piece of the Table1)
********************************************
...................
***********************
Page14 group is according to the first city
*******************************************************
GroupHeader2(first city name - Tablo1)
Masterdata2 (Table1)(Second piece of the Table1)
********************************

********************************
Page27 group is according to the first city
*************************
GroupHeader3(first city name - Tablo1)
Masterdata3 (Table1)(Third piece of the Table1)
***************************************

But I want to print 3 masterdata on the same page like above design because they are the same table data.

Help me please.
