I am trying to add and save multiples tables in a single CSV file, I have a car class and every car class inherits its own table but when I stop the program and check my CSV file out, only the table of car 3 appears out of 4 cars …Is it because I add the third car later in the program after 20 seconds,  
Regards

Hi,

You have two options :

- I assume `Car` is a class. Then you can declare a [static](https://processing.org/reference/static.html) attribute being a [Table](https://processing.org/reference/Table.html) object holding all the information of you cars.  
Then you can just keep adding columns with ` addColumn()`

- The second solution is to save a CSV file per instances of the class `Car`. It means that each instance is going to have a `Table` class as attribute. In order to save the table with different names for your cars, you can have an `id` for each instance (`saveTable(car_table, "car_" + this.id);`)
