 Format this table as binary data in the [Apache Arrow](https://arrow.apache.org/docs/js/) IPC format. The binary data may be saved to disk or passed between processes or tools. For example, when using [Web Workers](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers), the output of this method can be passed directly between threads (no data copy) as a [Transferable](https://developer.mozilla.org/en-US/docs/Web/API/Transferable) object. Additionally, Arrow binary data can be loaded in other language environments such as [Python](https://arrow.apache.org/docs/python/) or [R](https://arrow.apache.org/docs/r/).
