A structured table violates the declared record or column contract.

Member previewVariant 3 · 3 implementations · 8 checks per implementation

Case contract

Encode a list of text cells as TSV without a terminator. Escape backslashes before introducing backslash-t, backslash-n, backslash-r; preserve empty columns and all other text.

Why this case matters

Delimited interchange needs explicit framing, schema and field semantics at ingestion and emission boundaries.
