in reply to Passing two arrays to a subroutine

Use references. You cannot pass more than one array (or hash) without using a reference.
Column(\@act_table,\@colm);
...

sub Column {
    no warnings;
    my $actcol = shift;
    my $col = = shift;
    $colno++;
    print "In column : $colno\n";
    foreach (@$col) {
        print "$_\n ";
        $_=~s/(<Tc(?:\s?\;?\s?\;?\d?)?>)(.*)/Entity_convert($2)/eg;
        
        $_= ThinSpace($_);
        #print "***************** $_\n";
        
    }
}

You are not using @actcol in the subroutine, so why are you passing it?
Update: One reason why you might be getting "garbage values first" is because you are starting your array iteration at index 1 instead of zero.

    Thak you so much for your help

    However when i am passing arrays like this, It is adding one extra $_ in my array

    for ($h=0; $h<=$arg[1]-1; $h++) {
        my @colm="";
            for ($t=0;$t<=$arg[2]-1;$t++) {
                
                push @colm, $act_table[$t][$h];
                print "***##$act_table[$t][$h]\n";
                }
        
        Column(\@act_table,\@colm);
        }
                    
    
        
}

Alnfirstcol (@firstcol);  ## Sends first column for alignment to Subro
+utine Alnfirstcol    

#foreach my $item (@firstcol) {
    #print "$item \n";
#}

## Subroutine : Entity_conv
## Sends cellwise data to Entity module to convert entities
## After entity conversion sends cellwise data ThinSpace subroutine to
+ add thin space wherever required
## Sends column to Text_Nontext subroutine to evaluate whether column 
+is contains text data or non text data

sub Column {
    no warnings;
    
    
    my $actcol=shift;
    my $col=shift;
    $colno++;
    foreach (@$col) {
        print "$_\n";
        $_=~s/(<(?:Tr|Tc)(?:\s?\;?\s?\;?\d?)?>)(.*)/$1.Entity_convert(
+$2)/eg;
        }
    foreach (@$col) {
    #print "After ## $_\n";
    }        
        
    ThinSpace(\@$col,\@$actcol);
    return ();

}

      Using references does not change the array in any way. The problem must lie somewhere else - try to print, or better Data::Dumper, the array at various points in the program.
      BTW, instead of \@$col, you can use just $col.
