To define a column as a key, position on the appropriate line, click the Edit button, mark the Key checkbox, and click OK. If multiple keys are defined, precedence follows the order in the comparison. If no keys are defined, the alignment will use all of the columns to uniquely identify each row. By default, the files are sorted by their keys before the rows are aligned. Mark the Unsorted alignment checkbox to force the alignment to preserve the order of rows as they exist in the files. Note that this may cause rows with the same key column data not to be aligned. To control the alignment of columns By default, the comparison assumes the columns of the files are in the same order. To change the comparison order of a column in the left file, position on the appropriate line under Left file, and click the Move Up To control the names of columns By default, column names are automatically determined from the left or right file.

If left file data is available, you can pick Fill Names Using Left File from the list's right-click menu to force the names to be those found in the left file. Fill Names Using Comparison will force the names to be those that would be automatically determined.
