No parameters are used. Iterates over self.data_list, expecting each row to contain (Guid, Title, PubDate, Description). For each row, checks whether a local file documents/rss/{Guid}_rss_icon.jpeg exists; if so, serves it via /rssimage/; otherwise falls back to /image/blank_rss_icon.jpg. Returns an HTML string containing a <table> wrapped in a responsive div.
