I have a table in a database (Access 2013) that I want to sort by a particular column. But when I select the column, the Sort commands 'Ascending' and 'Descending' grey out. Strangely, at least to me, this only happens on some columns, while others in the same table will sort properly. The problem isn't restricted to a particular data type. Some numeric columns sort, others don't. Some alpha columns sort, others don't, etc. I've googled the problem but can't seem to find an answer. Can someone help me figure out how to make all columns sortable? TIA...
