Add `util.table(tabularData[, properties][, options])`, which renders tabular data with the same layout as `console.table` but returns it as a string instead of writing to a stream. This is useful for logging, writing to a file, or building output without a console. The row-building logic is extracted from `console.table` into a shared internal module so both APIs produce identical output. Signed-off-by: Daijiro Wachi <daijiro.wachi@gmail.com>

Would this be a lot faster if the shared helper were implemented in C++? |

There was a problem hiding this comment.
this should be a normal for loop - both for perf and to avoid needing a primordial for iteration
