Thanks for the plug-in - just what I was looking for. I tried the phpGrid plug-in but the lack of documentation or support was a bit disappointing. I'm having the same problem as a previous poster, in that I've installed the plug-in, set it up according to the instructions and am using the pre-supplied shortcode/table as a test. I can see the grid displayed, with field headings shown. I noticed that although the table exists in my db, it has no records. So, I added my wp_users table to the allowed list - this has over 500 records - and adjusted the shortcode accordingly. However, I still see no data in the grid. The field names are showing up, so the plug-in is clearly accessing the database. The only thing I noticed - and this probably isn't relevant - is that the table you provide is 'wpf - xxx@ whereas the plug-in is actually called 'wp_f xxxx' - notice the difference where the hyphen is. I can't see why that would matter, but thought I'd mention it. I also tried adding a row, but with no success. (i.e. clicked the 'add row' button - nothing happened)
Again, thanks for what looks like the start of a really great plug-in.
