Hi Mukunda,
Your question is not directly related to RadControls and RadSlidingPane but to general ASP.NET and CSS knowledge - if you just place a TABLE element in a simple DIV, you will get the same result. Please, nest a table in a DIv element and apply all the needed CSS to position it in order to meet your requirements. Once you get the desired result for the DIV just apply the same settings to the RadSlidingPane.
In case you succeed with the DIV implementation but you experience problems with the RadSlidingPane, share the DIV solution code here and I will apply the same CSS to the RadSlidingPane for you.
