If it is, converting to HTML will not display the grid.
The display that I posted is an jpg image, uploaded to photobucket
then post into the HTML tags that are supplied by RHT.
I am running a MAC so I use a program called GRAB which just grabs exactly what you want,
Example; open the program then select the section that you want to grab, or grab the whole window
save it as a JPG upload to photobucket then post it.
It seems alot to do, but real easy. It is the only way you will get the grid to display, HTML does not understand the grid lines
If you do decide to go this way I suggest you just save the the same spreadsheet as you edit then overwrite your upload.
