Closing line not appearing on Table split

Question

I am using Crystal Reports (Visual Studio 2005 version). The structure is as follows: Main Report Details Section has a Sub-Report embedded. The sub-report has: One Group Header - - One Details section Lines have been drawn manually to give table like appearance. Problem: When this table has lot of data and extends to more than one page in the main report the bottom line of the table gets truncated in the every page except the last page where the table actually closes. Is there any specific reason for this truncation? How to circumvent this problem?
