How to convert 2 column data into multiple columns based on a keyword in a row??

Hi Friends

I have the following input data in 2 columns.
Code:
SNo   1
I1  Value
I2  Value
I3 Value
SNo   2
I4  Value
I5  Value
I6  Value
I7  Value
SNo  3
I8  Value
I9  Value
...............
................
SNo N

I want the following output(Multi column)

Code:
SNo     1       SNo   2      SNo   3        ........SNo  N
I1      Value   I4    Value  I8    Value            Ix   Value
I2      Value   I5    Value  I9    Value            Iy   Value
I3      Value   I6    Value
                I7    Value

Ultimately I need a multi column output from 2 column input and needs to be segmented at the specified keyword. i.e. in this case SNo

I hope my problem statement is very clear.

Thanks in advance...

Small correction in the output. I7 Value should be below I6 Value. Because of formatting problem while posting it happened like that.

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. DIAGNOSTICS
The column utility exits 0 on success, and >0 if an error occurs. 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 " ; printf "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. BSD
