Question On Extracting Value Label and assign them as the column name of coefficient matrix

Hi, My question is about row names in matrix. Below are my code and its output.

Code:

    version 15.1
    sysuse auto.dta, clear
    reg price i.foreign, robust
    mat b = r(table)
    mat b = b[1..2, 2..3]'
    mat colnames b = "Car type" "Car type se"
    mat list b

              Car type  Car type se
1.foreign    312.25874    701.78135
    _cons    6072.4231    431.20837

As we know that, there are value labels for foreign, "Domestic" and "Foreign"

Code:

            tabulation:  Freq.   Numeric  Label
                            52         0  Domestic
                            22         1  Foreign

So, my question is that how can I extract the value label of "foreign" and assign that values labels to the matrix I made above as the row name of this matrix?

Thanks a lot!
