Ability to disable text alignment in cells

Currently table cells are aligned to the left by default.
That makes impossible to render formatted YAML sampes in cells:

```
╭───────┬─────────────────────────────────────────────────────╮
│ repo │ result │
├───────┼─────────────────────────────────────────────────────┤
│ users │ origin/branch-name: │
│ │ authors: │
│ │ - name@domain │
│ │ - name@domain │
│ │ lastcommit: "2023-03-17T20:41:03+03:00" │
╰───────┴─────────────────────────────────────────────────────╯
```

It would be nice to be able to render formatted YAML, like this:

```
╭───────┬─────────────────────────────────────────────────────╮
│ repo │ result │
├───────┼─────────────────────────────────────────────────────┤
│ users │ origin/branch-name: │
│ │ authors: │
│ │ - name@domain │
│ │ - name@domain │
│ │ lastcommit: "2023-03-17T20:41:03+03:00" │
╰───────┴─────────────────────────────────────────────────────╯
```

No file or test is named in the issue. Start by locating the Go code that renders table cells and applies text alignment, then trace how multiline cell content is handled. Done means callers can disable alignment so formatted YAML indentation is preserved, with coverage for the shown output.
