{"version":"1.0","type":"rich","title":"0509sample","description":"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.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ef858b47d2164dc484b3bb618a604503?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
