Shall we have a new section called Tables and make these configs under a sub-section Write properties. I think it may be better to separate the general table properties from configurations of FileIO and Catalogs, which are more vendor specific.

Also, I think we can write a note in the new section, indicating that currently pyiceberg write only support certain table write properties. WDYT?


| Key | Options | Default | Description |
| --------------------------------- | --------------------------------- | ------- | ------------------------------------------------------------------------------------------- |
| `write.parquet.compression-codec` | `{uncompressed,zstd,gzip,snappy}` | zstd | Sets the Parquet compression coddec. |
| `write.parquet.compression-level` | Integer | null | Parquet compression level for the codec. If not set, it is up to PyIceberg |
| `write.parquet.page-size-bytes` | Size in bytes | 1MB | Set a target threshold for the approximate encoded size of data pages within a column chunk |
| `write.parquet.dict-size-bytes` | Size in bytes | 1MB | Set the dictionary page size limit per row group |

Below the FileIO specific configuration is shown.
