LH Downloadable Tables adds a Download table button to HTML tables, so visitors can save a table’s contents as a CSV file and open it in a spreadsheet. It is useful for results, ladders, rosters and any other tabular data people want to keep or work with.
Give a table the class downloadable and a caption, and the button appears in the caption. The download happens entirely in the browser: no data is sent to the server and nothing is stored.
data-download_filename attribute on the table; the date is added automatically.
