Nested Objects support

If I have an Object :
```
{
id: 123,
name: "abc",
properties: {
color:"green" ,
email: "xyz@email.com"
}
}
```

I want to create a table with id, name and color only and not show email like this:
| ID | NAME | COLOR |
| ----------- | ----------- | ----------- |
| 123 | abc | green |
| 234 | xyz | red |

How can I do this?

No source file or test is named in the issue. Start by locating the Vue2 table component's data and column-handling entry points, then check how nested properties are currently read. Done means a nested properties.color value can appear as COLOR while properties.email remains excluded from the rendered table.
