In the below given example like rejection date it has total 5 rows of same type. when i tried to create new data block item like issue date(issue date is table column) I'm getting only one row (I want to get 5 rows as shown below.)
Forms does that itself, but you have to add that new item into that block. Because, it is
that affect number of "rows" you'll see.
For example, if block's number of records displayed is set to 5 (as it apparently is) and you add a new item to that block and set appropriate canvas, Forms will create 5 instances of that item. You can then choose not to display all of them but any number between 0 and 5 (where "0" also means "all of them" (5 in this case)).
