I don't think any column limitation of a table can be possible. But size limitation is there. So basically it depends on the columns data type that you are going to enter in a particular columns.
So if you have 10 byte limitation for a particular row in a table. You can take 5 columns of int type(here integer length is 2 byte). Or may be 4 int column and 2 char column(here int is of 2 byte and char is of 1 byte).
