Merging cells is easily done and can help make a spreadsheet look neat, but what you really, really should be doing instead is centering across the selection so it looks merged but isn’t. Center across selection though is hidden away and therefore time-consuming to use – no wonder people have bad habits! I wanted to do things the better way, but was lazy, so in the end I made a macro to go in my personal workbook and assigned it to my ribbon (I do this a lot).
The macro is
Sub CenterAcrossSelection() With Selection .HorizontalAlignment = xlCenterAcrossSelection .VerticalAlignment = xlBottom .WrapText = False .Orientation = 0 .AddIndent = False .IndentLevel = 0 .ShrinkToFit = False .ReadingOrder = xlContext .MergeCells = False End With End Sub
