/**
 * Combines multiple DataTables into a single DataTable.
 *
 * Merges rows from all input tables. Columns are matched by name and type;
 * columns that don't exist in all tables will have undefined values for
 * rows from tables lacking that column.
 *
 * If tables have differing source transforms, all data is first converted
 * to engine coordinate space (identity transform) before combining.
 *
 * @param dataTables - Array of DataTables to combine.
 * @returns A new DataTable containing all rows from all input tables.
 *
 * @example
 * ```ts
 * const combined = combine([tableA, tableB, tableC]);
 * console.log(combined.numRows); // tableA.numRows + tableB.numRows + tableC.numRows
 * ```
