# for i in {1..9}; do for j in $(seq 1 $i); do echo -ne $i×$j=$((i*j))\\t;done; echo;done

Result : 

#1×1=1

2×1=2 2×2=4

3×1=3 3×2=6 3×3=9

4×1=4 4×2=8 4×3=12 4×4=16

5×1=5 5×2=10 5×3=15 5×4=20 5×5=25

6×1=6 6×2=12 6×3=18 6×4=24 6×5=30 6×6=36

7×1=7 7×2=14 7×3=21 7×4=28 7×5=35 7×6=42 7×7=49

8×1=8 8×2=16 8×3=24 8×4=32 8×5=40 8×6=48 8×7=56 8×8=64

9×1=9 9×2=18 9×3=27 9×4=36 9×5=45 9×6=54 9×7=63 9×8=72 9×9=81

Change the value {1..9} and see the magic.

like this :

# for i in {2..9}; do for j in $(seq 1 $i); do echo -ne $i×$j=$((i*j))\\t;done; echo;done

2×1=2 2×2=4

3×1=3 3×2=6 3×3=9

4×1=4 4×2=8 4×3=12 4×4=16

5×1=5 5×2=10 5×3=15 5×4=20 5×5=25

6×1=6 6×2=12 6×3=18 6×4=24 6×5=30 6×6=36

7×1=7 7×2=14 7×3=21 7×4=28 7×5=35 7×6=42 7×7=49

8×1=8 8×2=16 8×3=24 8×4=32 8×5=40 8×6=48 8×7=56 8×8=64

9×1=9 9×2=18 9×3=27 9×4=36 9×5=45 9×6=54 9×7=63 9×8=72 9×9=81
