Render Variable: - Specify a variable based on which object can be conditionally rendered.
Style Variable: - Specify a variable based on which object can be conditionally styled.
Example for Style Variable
In a report in a list if u want to display every alternate row with particular color
in this case
1) create a data item with name running-count with function "running-count" on particular unique column
2) now create one more data item as mod with functon "mod" on that running-count data item
3)create a boolean varibale with expression mod 1
4)go to the page select List column Body style
5)In properties pane select Style Variable as boolean variable
6)click on YES variable and set its Foreground color as RED
7)click on No variable and set its Foreground color as Yellow
now run the report
