I would like to order a column containing characters like this: 

```
K3SG1-105-1051-1

```

However, using the arrange function will result in this: 

```
K3SG1-105-1051-1

K3SG1-105-1051-10

K3SG1-105-1051-100

K3SG1-105-1051-1000

```

Instead of what I want:

```
K3SG1-105-1051-1

K3SG1-105-1051-2

K3SG1-105-1051-3

K3SG1-105-1051-4

```

Thanks in advance.
