Hi Sudheesh,
You should be able to use a repeating section and conditional formatting to do this. You could also do some manual xsl editing to get it to work, but that's more work. Please try converting your repeating table into a repeating group of two sections with different backgrounds which conditionally show depending on the state of the checkbox. I hope this is enough info for you to get it to work. Good luck!
