css conflict with repeater rows

hi  @ptasker,

please remove or change the selector for this css code:

```
.acf-table {
	table-layout: fixed;
}
```

found here: https://github.com/ptasker/acf-code-field/blob/master/css/input.css

currently there is a bug with the repeater field - you see it when dragging there to another position.
