## 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.
