WebGrid has a feature called ColumnSet. It is capable to render a subset of cells and rows as one row unit. This allows true cell layouting without dependency to column object. It also enables you to construct the layout dynamically from your codes.

I'm sure that the ColumnSets feature fits well with your scenario. For more detail information about ColumnSets layout, please check the documentation in here.

can I add column dynamically with column set?

Yes, you can. Please refer to the How-to: Create ColumnSet layout programmatically article in here.
