## Dataset Structure

### Data Instances

#### default

- **Size of downloaded dataset files:** 
- **Size of the generated dataset:** 
- **Total amount of disk used:** 

An example of 'validation' looks as follows:
```
{
    "id": 0,
    "column_index": 3,
    "label": "currency",
    "table": {
        "name": "Book_7sat.co.uk_September2020_CTA.json.gz",
        "header": ["col1", "col2", ...]
        "rows": [
           ["2001", "2", "USL A-League", ...],
           ["2002", "2", "USL A-League", ...], 
           ...
        ]
    }
}
```

### Data Fields

The data fields are the same among all splits.

#### default
- `id`: a `int32` feature.
- `column_index`: a `string` feature.
- `label`: a `string` feature.
- `table`: a dictionary feature containing:
  - `rows`: a `list` of `string` features.
  - `rows`: a `list` of `list` of `string` features.
  - `name`: a `string` feature.
