This example shows a simple HTML table with column merging, where the header row contains a cell that spans three columns using the `colspan` attribute. The table displays static text content in Korean, with a border and fixed width set through inline CSS styles. Built with plain HTML and CSS, it demonstrates basic table structure and layout without JavaScript or external libraries. The page includes a section and article wrapper, though no styling rules are defined in the style tag, leaving the browser defaults mostly intact.
