Hi,
I want to hide the empty columns and fill the gap with next field in crystal report.
ex:
i have
col1 col2 col3
val1 val2 val3

i used the suppress option with formula --

if isnull({val2}) true else false

if val2 is empty then its displaying the report as

col1 whitespace col3
val1 whitespace val3

instead i need to display it as

col1 col3
val1 val3

Thank you
