Displaying column contents of a table in hierarchical manner

Hi all,

I have got a few requirements in VC which are :

1) I need to display the column contents of a table in hierarchical manner.

2) we have an input field which needs to display and calculate the date in ww/yyyy format but whenever we are deploying the code we are getting the error. But works well with ww.yyyy format. Is there any way using which we can display the contents using ww/yyyy format without any errors.

Knowing whether it's possible from VC end or not will also be helpful.

Thanks in Advance...
