Updated: 2026-07-17

## Example

```python
t.columns               # ['name', 'score']
"score" in t            # True — membership tests a column name
len(t)                  # row count
```

## Notes

`columns` is a plain `list[str]`, in schema order. To test whether a column exists, use
`name in table`; for the full types use [`schema`](/docs/api-table-schema).
