Sometimes a list is not enough: you need the numbers laid out in rows and columns - a multiplication sheet, a counting grid for a lesson, a reference rectangle of consecutive values. A numbers table turns one start value into a full rectangle: pick the rows, the columns, the step between neighbors, and the grid fills itself left to right and top to bottom, every cell exactly one step ahead of the last.
Numbers Table Generator builds grids of up to 4,000 cells and renders them in four bases - decimal, hexadecimal, octal and binary - so the same rectangle doubles as a base-conversion classroom. Copy hands over a tab-separated grid ready for a spreadsheet; download writes it as a text file. All generation runs locally in the browser.
