This PR introduces ability to set styles for individual columns in table. For example, we can apply STR_PAD_LEFT for the last column (useful for money, file size etc).

Code:
```php
use Symfony\Component\Finder\Finder;
use Symfony\Component\Console\Helper\Table;
use Symfony\Component\Console\Helper\TableStyle;

$table = new Table($output);
$table->setHeaders(['#', 'Path', 'Size']);

$style = new TableStyle();
$style->setPadType(STR_PAD_LEFT);

$table->setColumnStyle(2, $style);

$finder = new Finder();
$finder->files()->in("/path/to/dir")->name('*.php')
$counter = 0;
foreach ($finder as $file) {
    $counter++;
    $table->addRow([$counter, $file->getRealPath(), number_format($file->getSize(), 0, '.', ' ')]);
}

$table->render();
```
Output:
```
+---+---------------------+--------+
| # | Path                |   Size |
+---+---------------------+--------+
| 1 | autoload.php        |    183 |
| 2 | ApplicationTest.php | 47 794 |
| 3 | CommandTest.php     | 14 965 |
| 4 | ListCommandTest.php |  2 369 |
