Do people bring gifts to weddings ?

So my wedding is in May and I am organizing where the tables are gonna go how everything will be set up on them. It is in my in-laws backyard and it’s about 50 people and I have and continue to be the main planner and I stress detail.. I have only been to one wedding where my husband was a groomsman and we didn’t bring a present I don’t think and i didn’t see a spot for them. But a few people mentioned presents and now I’m like okay do i need to make a spot for them ? I don’t wanna do that and then people feel weird they didn’t bring anything. And if they do I don’t open them there right I take them home ? I know I’m nuts. Was too crazy about detail lol
