echo - How can I align the columns of tables in Bash?

Question

I'd like to output a table format text. What I tried to do was echo the elements of an array with '', but it was misaligned.

My code

for((i=0;i<array_size;i++));
do
   echo stringarray[$i] $'' numberarray[$i] $'' anotherfieldarray[$i]
done;

My output

a very long string..........     112232432      anotherfield
a smaller string         123124343     anotherfield

Desired output

a very long string..........     112232432      anotherfield
a smaller string                 123124343      anotherfield
