To make the best use of space in the user's terminal I would like to arrange tables side-by-side similar to the above example. I looked into the possibility of nesting these tables inside a parent table, but I'm not sure if that's possible.

The key is to use Symfony's BufferedOutput class. Here's an example in the form of a Symfony Console command:

<?php

namespace Wps\Console\Commands\Update;

use Robo\Common\OutputAwareTrait;
use Symfony\Component\Console\Helper\Table;
use Symfony\Component\Console\Helper\TableStyle;
use Symfony\Component\Console\Output\BufferedOutput;
use Wps\Console\RawBufferedOutput\RawBufferedOutput;

class NestedTablesCommand extends \Wps\Console\Commands\WpsCommandBase {

  use OutputAwareTrait;

  protected $outputBuffer;

  /**
   * @command nested
   */
  public function execute() {
    $this->setOutputBuffer();
    $this->parentTable();
  }

  protected function setOutputBuffer() {
    $this->outputBuffer = new RawBufferedOutput();
  }

  protected function parentTable() {
    $table = new Table($this->output);

    $tableStyle = $this->parentTable->getStyleDefinition('box');
    $tableStyle
      ->setPadType(STR_PAD_BOTH);
    $table->setStyle($tableStyle);

    $this->topLeftChildTable();
    $topRightChild = $this->outputBuffer->fetch();
    $this->bottomRightChildTable();
    $bottomRightChild = $this->outputBuffer->fetch();

    $table->setHeaderTitle('Parent Table');
    $table->setheaders(['Left', 'Right']);
    $rows = [
      [$topRightChild, 'r1'],
      ['l2', $bottomRightChild],
    ];
    $table->setRows($rows);
    $table->render();
  }

  protected function topLeftChildTable() {
    $table = new Table($this->outputBuffer);
    $table->setStyle('box');
    $tableStyle = new TableStyle();
    $tableStyle
      ->setPadType(STR_PAD_BOTH);
    $table->setHeaderTitle('TL Child');
    $table->setheaders(['Left', 'Right']);
    $rows = [
      ['L1', 'R1'],
      ['L2', 'R2'],
    ];
    $table->setRows($rows);
    $table->render();
  }

  protected function bottomRightChildTable() {
    $table = new Table($this->outputBuffer);
    $table->setStyle('box');

    $tableStyle = new TableStyle();
    $tableStyle
      ->setPadType(STR_PAD_BOTH);
    $table->setHeaderTitle('BR Child');
    $table->setheaders(['Left', 'Right']);
    $rows = [
      ['L1', 'R1'],
      ['L2', 'R2'],
    ];
    $table->setRows($rows);
    $table->render();
  }

}

In order to preserve the ANSI code decorations when we render the tables to the buffer, we need to extend BufferedOutput:

<?php

namespace Wps\Console\RawBufferedOutput;

use Symfony\Component\Console\Output\Output;

class RawBufferedOutput extends \Symfony\Component\Console\Output\BufferedOutput {

  public function write($messages, $newline = FALSE, $options = self::OUTPUT_NORMAL) {
    parent::write($messages, $newline, self::OUTPUT_RAW);
  }

  public function writeln($messages, $options = self::OUTPUT_NORMAL) {
    parent::writeln($messages, $options, self::OUTPUT_RAW);
  }

}

This renders:
