'20 in {0,20}, defines the width of the column
'If it is negative i.e. -20, then the text is left aligned
'within the column otherwise it is right aligned in the column
	'line = String.Format("{0,20}{1,20}" & vbLf, animals(i), fruits(i))
	line = String.Format("{0,-20}{1,-20}" & vbLf, animals(i), fruits(i))
'If 20 spaces are to be introduced between two words then
'the following code can be used.
	'line = String.Format("{0}{1}{2}" & vbLf, animals(i), spaces, fruits(i))
	sb.Append(line)
	i += 1
End While
