As a stop-gap, I'd recommend exporting your file as comma-separated values, opening the result in Notepad, and search-and-replacing the commas with [td] tags; you can then run down the lines and add [tr] tags to each one. No need for closing tags, except for [/table]. If your data contains commas, save it as tab-separated values and then copy and paste a tab into the search-and-replace box.
