Bash does not support multidimensional arrays.
You can simulate them for example with hashes, but need care about the leading zeroes and many other things.

for example :

var="id1 name1 key1"

declare -A matrix
num_rows=1
num_columns=3

read -a array <<< ${var}

matrix[1,1]=${array[0]}
matrix[1,2]=${array[1]}
matrix[1,3]=${array[2]}


for ((j=1;j<=num_columns;j++)) do
    for ((i=1;i<=num_rows;i++)) do
        echo ${matrix[$i,$j]}
    done    
done
