Different datetime formats in columns

May 30 at 4:32 PM

In my export I have columns with datetime, string and decimal values. For every datetime column I defined "Style.Numberformat.Format" as date only "mm-dd-yy". But now I need for some columns date and time. So I changed format to "mm-dd-yy hh:mm:ss". But this not worked. In xlsx style is only first definition for date only. Is possible this somehow defined?
