The code you provided seems to have some errors. It refers to 'rows' and 'columns' which are not defined anywhere. If we assume that 'rows' is 'arr' and 'columns' is the length of the sublists in 'arr', the code should look like this:

```python
arr = [[123],[456]]
for i in range(len(arr)):
for j in range(len(arr[i])):
print(arr[i][j],end=" ")
print("
")
```

However, this will print '123 456', not '1 2 3 4 5 6' or '123456'. If you want to print each digit separately, you need to convert the numbers to strings first and iterate over the characters. Here is how you can do it:

```python
arr = [[123],[456]]
for i in range(len(arr)):
for j in range(len(arr[i])):
for digit in str(arr[i][j]):
print(digit,end=" ")
print("
")
```

This will print '1 2 3 4 5 6'.
