Tables offers different options to present data as a number, an amount, a percentage or as date & time.

You are able to exactly specify the format for numbers by setting up the number of decimal points or by displaying a separator. Further on you can specify a prefix or suffix as well as displaying negative values in red.
For date & time you can choose the display format depending on your local system settings. By that you are able to specify whether and how to display the date, the time or both.
If the system formats for date & time are insufficient you are able to define an individual format for date & time.

If you don't want to search for the format string in the whole user's guide book you can just use an assistant to compose a format string.
