Creating Matrix from file

Hi all, I'm a newbie in shell scripting and currently I'm trying to create a matrix using bash. The Output will look like this

Code:
               AB   CDE   FG
 1   
2   
3
4
5
6
7

I'm stuck on the ABCDEFG display.

Code:
printFlightSeats()
{

rows=7
columns=7
for ((i=0;i<=$rows;i++))
do
    echo -n "$i" | tr "0" " "
    for ((j=0;j<$columns;j++))
    do  
    echo -n "$j" | tr "0" " " | tr "1234567" "ABCDEFG"
        
    done
    printf $j
    printf "$i\n"
done

}

Can anyone advise me? Thanks in advance!Smilie

irsend - basic LIRC program to send infra-red commands SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
