On the wedding day, both parents were present. How to arrange it? thank you

It's normal for both parents to be here. Here, men and women hold a banquet together.

When the ceremony was held, both parents came to the stage together and delivered speeches respectively, wishing their children a happy marriage.

However, the banquet is a table for the man's parents and a table for the woman's parents. If only your parents are present and other relatives are absent, both parents can sit at the same table.
