Here is an awk solution:

Code:
$ awk '{if (substr($0,4,4)=="    ") {print substr($0,1,2),save,substr($0,9);} else {save=substr($0,4,4); print $0}}' file.txt

Code:
awk '{if($2 == ""){$2=A}} {A=$2} 1' Input_file

RavinderSingh13's awk solution above does not appear to work as is since $2 will be valued from a different column (e.g 30010)when the expected field is missing (as file is column delimited).

column

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME

     column -- columnate lists

SYNOPSIS

     column [-tx] [-c columns] [-s sep] [file ...]

DESCRIPTION

     The column utility formats its input into multiple columns.  Rows are filled before columns.  Input is taken from file operands, or, by
     default, from the standard input.	Empty lines are ignored.

     The options are as follows:

     -c      Output is formatted for a display columns wide.

     -s      Specify a set of characters to be used to delimit columns for the -t option.

     -t      Determine the number of columns the input contains and create a table.  Columns are delimited with whitespace, by default, or with
	     the characters supplied using the -s option.  Useful for pretty-printing displays.

     -x      Fill columns before filling rows.

     Column exits 0 on success, >0 if an error occurred.

ENVIRONMENT

     COLUMNS  The environment variable COLUMNS is used to determine the size of the screen if no other information is available.

EXAMPLES

	   (printf "PERM LINKS OWNER GROUP SIZE MONTH DAY HH:MM/YEAR NAME
" 
	   ; ls -l | sed 1d) | column -t

SEE ALSO

     colrm(1), ls(1), paste(1), sort(1)

HISTORY

     The column command appeared in 4.3BSD-Reno.
