Add a row to a table

Goal: Append a new row of data to an existing Markdown table.

Prerequisites: The table module, via -A or nodes.

Query

$ mq -A 'import "table" | table::tables | first | table::add_row(["Charlie", "35"])' README.md

Input

| Name  | Age |
| ----- | --- |
| Alice | 30  |

Output

| Name    | Age |
| ------- | --- |
| Alice   | 30  |
| Charlie | 35  |

Notes

• add_row takes a plain array of cell values, in column order — it will error if the array’s length doesn’t match the table’s column count.
• Column widths are re-computed to fit the new data, which is why Alice gets re-padded alongside Charlie.
• No table::to_markdown call needed here — mq expands table objects to Markdown automatically in query output. See Extract all tables from a document for when to_markdown actually is required.
