Table is an alias for Str[dyn][dyn]: a vector of rows of cells. It is what `using` yields from a CSV, what a raw SQL query answers with, and what hive.map.toTable builds. A bare `using "path"` reads a comma-separated file; adding `as csv separating by "<sep>"` picks a different delimiter, such as a tab for a TSV — and every form answers with a Result, so the source says exactly which reader the build needs to link in.
