She got to pretty numbers in the end, but if you look at the first week or so there was nothing pretty about that at all! Her reading on diagnosis was 680 and I really never thought it would be possible for her to reach remission from such a high starting point. But she did, and so far (anti-jinx) she's been diet controlled for a little over a year now. So never give up hope!
I selected the row I wanted to put the OTJ trial header on and merged the cells in the row so that all the boxes in that row turn into one big box. Then I typed in the information I wanted and used the 'horizontal align' button at the top of the spreadsheet to center the writing. Finally, because I wanted a different color for those rows than anything I was using anywhere else, I selected the row and used the 'fill' button (the one that looks like a paint can) to make the row a different color from everything else.
