table_read_csv — FILEIO `table` op

• Data kinds: text → table

• Call: import fullseye as fs; fs.ledger.table_read_csv(text) (to call the implementation directly, import fileio; fileio.table_read_csv(text); from the registry, opsfileio.get("table_read_csv"))

• GPU: none (CPU reference implementation only)

Usage

Reads the unit-aware CSV produced by table_write_csv and returns a table containing columns, units, and metadata.

> The detailed description below is the original text — the summary and the headings are translated.

返り値は {"columns": {列名: 1-D 配列}, "units": {...}, "meta": {...}}。列名と単位の個数、全データ行の列数、必須メタデータを検査し、途中までの表は返さない。数値列は float64 (空欄は NaN)、数値以外を含む列は文字列配列になる。入力は UTF-8 の str または bytes。

呼び出し例: roundtrip = table_read_csv(table_write_csv(table, units=units, meta=meta))。
