Add Tables Cell at runtime

Hi
I would like to add some cells to add some rows to a table and format the
cells, add them content and individually all based on the current record
shown.

Can that be done without using the place holder method but something like
table.addrow in which case how can I assign the required table to the object
(how can that be identified)
then I will need to assign css class to individual cells that were added

Thank you in advance,
Samuel
