Renaming a column does not select it for output. The use of any justification flags implies that all the columns will be justified. Justification options that are listed on the command line apply to all following columns until a different option is given. The default justification is left for text and right for numbers. Justify the column with its default justification.
Numeric values are right justified and text is left justified.
Expand the column. Care should be taken with the width option, column data will be truncated if they are width than the width specification. Skip the data in the column. Delete the column. Pass the column through with no justification.
