Format-Table with centered calculated property misaligns the column label

[mklement0]

This is a regression from Windows PowerShell.

Steps to reproduce

[pscustomobject] @{ one = 1 } |
  Format-Table @{ l='one'; e='one'; width=10; alignment='center' }

Expected behavior

   one
   ---
    1

Actual behavior

one
   ---
    1

Note how the column header (one) is misaligned.
