What approach would you use in this case?

Hi! I am building a table for logistic transports in our app, and one of the requirements defined by the product manager is that the transports should be grouped in the table when they belong to the same group. How would you achieve this? Can I use the grouping API that the library offers, or is it more focused on grouping columns instead of rows? I have attached a picture with the desired design. As you can see, the first row in the second table is a group of rows. Thanks in advance!
