Column Heading
Column IV is not the last column in Excel 2007, as it was in Excel 2003. In Excel 2003 the last column is IV which is column 256. In Excel 2007 the last column is XFD, which is column 16384.

That depends on the version. Up to version 2003, it was row 65,536. From Excel 2007 onwards, it is row 1,048,576.
The letters in the heading above a worksheet grid are called column names.
XFD is the column label on the last column in a Microsoft Excel 2007 worksheet.
It would use the data in the column as the basis for the sorting and sort the rest of the data.

The author of this question categorised it in Microsoft Excel. I am not aware of anything called "swim lanes" related to MS Excel. However, you can highlight a column by clicking on the column heading (the letter of the column at the top of the screen).
Column headings start at A. After reaching Z, the next is AA, then AB and so on. What the last column is will depend on the version of Excel that you have. Column IV, which is the 256th column, is in the versions up to Excel 2003. From Excel 2007 there are 16,384 columns and last one is column XFD.
