Merging cells mid table in Numbers
In the middle of a table I wish to put a 'brea' a row that is a explanation of the calculations below it. I want to Merge all the cells from all columns. But it seems that because the first two columns are header columns, the Merge function is greyed out.
How do I go about resolving this . I am guessing that there is some way to ' reset ' a group of select cells to default / base no formatting 'format' in order to allow me to merge these cells?
I can't find it
Help appreciated.
Thanks
