How to empty the $table every iteration drawn using Text::SimpleTable - perl

Question

#!/tool/pandora64/bin/perl5.18.1
use strict;
use warnings;
use Text::SimpleTable; my $a=1;my $b=2; my $c=3; my $d=4; my #p_arr = (1,2);
my $table = Text::SimpleTable->new([1, "A"], [2, "B"], [3, "C"], [4, "D"]);
foreach my $p(#p_arr){
$table->row($a,$b,$c,$d);
$a=$a+1; $b=$b+1; $c=$c+1; $d=$d+1;
print "\nAfter $p iteration\n";
print $table->draw;
}
I need to print the table, but after the first iteration it is appending. How can I empty the table after every iteration?
Output I get:
After 1 iteration
.----+----+-----+------.
| A | B | C | D |
+----+----+-----+------+
| 1 | 2 | 3 | 4 |
'----+----+-----+------'
After 2 iteration
.----+----+-----+------.
| A | B | C | D |
+----+----+-----+------+
| 1 | 2 | 3 | 4 |
| 2 | 3 | 4 | 1 |
'----+----+-----+------'
Expected after 1st iteration:
.----------------
| A | B | C | D |
+----------------
| 1 | 2 | 3 | 4 |
+----------------
Expected 2nd iteration:
.----------------
| A | B | C | D |
+----------------
| 2 | 3 | 4 | 5 |

Simply move the call to new inside the foreach loop. This creates a new table each time through the loop:
use strict;
use warnings;
use Text::SimpleTable; my $a=1;my $b=2; my $c=3; my $d=4; my #p_arr = (1,2);
foreach my $p(#p_arr){
my $table = Text::SimpleTable->new([1, "A"], [2, "B"], [3, "C"], [4, "D"]);
$table->row($a,$b,$c,$d);
$a=$a+1; $b=$b+1; $c=$c+1; $d=$d+1;
print "\nAfter $p iteration\n";
print $table->draw;
}
Prints:
After 1 iteration
.----+----+-----+------.
| A | B | C | D |
+----+----+-----+------+
| 1 | 2 | 3 | 4 |
'----+----+-----+------'
After 2 iteration
.----+----+-----+------.
| A | B | C | D |
+----+----+-----+------+
| 2 | 3 | 4 | 5 |
'----+----+-----+------'
If you want the width of all the columns to be the same, you can use the same number in the call to new:
my $table = Text::SimpleTable->new([1, "A"], [1, "B"], [1, "C"], [1, "D"]);
The POD doesn't specify what the arguments to new are, so I had to look at the source code.
