Rule 2: Never leave one heading cell blank. You will find that you do this if you add a temporary column. If you forget to add a heading before you sort, this will completely throw off the IntelliSense, and Excel will sort the headings down into the data.
Rule 3: There should be no entirely blank rows or blank columns in the middle of your data. It is okay to have an occasional blank cell, but you should have no entirely blank columns.
Rule 4: If your heading row is not in row 1, be sure to have a blank row between the report title and the headings.
Rule 5: Formatting the heading cells in bold will help the Excel’s IntelliSense module understand that these are headings.
Gotcha: List format won’t help at all if your data is only two columns wide.
Results:If you follow the list format rules,Excel’s IntelliSense will allow all the data commands to work flawlessly.
