I talked about this project before. You can now use it here : http://latex-tables.com. It supports many features including borders, merging cells, slashboxes, rotated cells and more.
You can import tables from LaTeX and CSV, or import tables via copy/paste from webpages, Word documents, Excel and more.
You can export your tables to LaTeX, Plain TeX (first and only online editor to allow this feature), HTML and Markdown. More formats are coming soon !
