I have an SSRS report and I have a table there, in which I have a column named as No. Of Days which are lying between two dates. I am getting those dates (datetime) through datasource but don't know how to calculate number of days between these two dates in a tablix cell formula.

The following will get the difference between two dates:
=DateDiff("d","01-Jun-2011","10-Jun-2011")
which results in 9.
In a table cell it will be something like:
=DateDiff("d",YourDataSet.Fields!FirstDate.Value, YourDataSet.Fields!SecondDate.Value)
