Let's say a table:

```
t = {
    { name = "Bob", age = 34, gender = "Male"},
    { name = "Bill", age = 40, gender = "Male"},
    { name = "Barbara", age = 20, gender = "Female"}
}

```

Using name as an index, what do I need to do to return or print the age of Bob or the gender of Barbara?

More precisely, a function to call for age and another for gender when the name is "Bob", or any other.
