I would like to print out an list of reals in a table with perfectly identical number of digits so that they can be perfectly right-aligned. However, once I convert them to strings, TableForm no longer prints them in a column:

  TableForm[RandomReal[1, 20], TableAlignments -> Right]
  TableForm[NumberForm[RandomReal[1, 20], {5, 3}], TableAlignments -> Right]

The first output has an inconsistent number of digits. The second is horizontal. Is there a good workaround for this issue?

NumberForm[#, {5, 3}] & /@ RandomReal[{0, 1}, 20] // TableForm

  • $\begingroup$ Can you explain structure of this? What kind of object does TableForm return and why does NumberForm apply to it? $\endgroup$
