I use an Excel spreadsheet for daily reporting of lithology in a strip mining site. The sheet has fields used as checkboxes, with accompanying labeling. The top of the sheet is just date and location (using coordinates) fields, and the right half of the sheet consists of labeled checkboxes. The left half of the sheet is used for describing the lithology at the time of the inspection.
I have all the fields used for labeling locked, and the sheet protected, so that the only fields that can be selected are the fields that actually need input. The problem I’ve encountered is in the open field for lithology. Depending on the lithology, this field is usually divided into from 3 to 5 strata, with descriptions.
Ideally, I want to select the depth of the field (in rows), merge all those cells and type in a description centered horizontally and vertically, and delineate the lower boundary of the field with a thick border. However, when I select the desired area and try to format, the “Merge cells” checkbox is filled with a black rectangle, greyed out, and can’t be selected. I can mark the lower boundary with a thick border, but I can’t merge the cells.
If I unprotect the sheet, I can merge the cells. But protected, even though all those cells are unlocked, I can’t merge them. What am I overlooking?
