What Is Markdown Table Generator?
A Markdown Table Generator is a tool that allows users to create markdown tables through a visual interface, eliminating the need to manually type complex syntax. Developers and writers who use GitHub markdown tables frequently can benefit from it, as one specific problem it solves is the tedious process of formatting tables with precise pipe characters and dashes. For instance, when creating a markdown table for documentation purposes, it can be frustrating to ensure proper alignment and spacing.
The tool stands out due to its ability to dynamically adjust column widths based on cell content, ensuring that the generated markdown table syntax is properly formatted. It also features customizable column alignment options, including left, center, and right, which can be cycled through with a single button click. Additionally, it includes controls for setting the number of columns and rows, making it easy to create tables of varying sizes.
It allows users to fill in cells in an intuitive grid interface, similar to a spreadsheet, and then generates properly formatted markdown table syntax. The output is automatically formatted with proper spacing and alignment markers, including the use of colons and dashes to define column boundaries. This makes it easier for users to create markdown tables without having to learn complex syntax, such as how to create a markdown table or understanding github markdown table specifics.

Technical Guide
The generator maintains a 2D array of cell values with an additional alignment array for column configuration. The first row is treated as the header row. When generating Markdown output, the tool calculates the maximum width of each column to produce evenly-padded output. The separator row between header and body uses dashes with optional colon markers for alignment: left-aligned uses no colons (default), center-aligned uses colons on both sides (:---:), and right-aligned uses a colon on the right (---:). Cells are padded with spaces to the column width using String.padEnd(). The result is a cleanly formatted Markdown table that renders correctly in any Markdown parser.
