+Modifying Rendered Tables
+-------------------------
+
+.. versionadded:: 4.1
+    The feature to modify rendered tables was introduced in Symfony 4.1.
+
+The ``render()`` method requires passing the entire table contents. However,
+sometimes that information is not available beforehand because it's generated
+dynamically. In those cases, use the
+:method:`Symfony\\Component\\Console\\Helper\\Table::appendRow` method, which
+takes the same arguments as the ``addRow()`` method, to add rows at the bottom
+of an already rendered table.
+
+The only requirement to append rows is that the table must be rendered inside a
+:ref:`Console output section <console-output-sections>`::
+
+    use Symfony\Component\Console\Helper\Table;
+    // ...
+
+    class SomeCommand extends Command
+    {
+        public function execute(InputInterface $input, OutputInterface $output)
+        {
+            $section = $output->section();
+            $table = new Table($section);
+
+            $table->addRow(['Row 1']);
+            $table->render();
+
+            $table->addRow(['Row 2']);
+        }
+    }
+
+This will display the following table in the terminal:

+Output Sections
+~~~~~~~~~~~~~~~
+
+.. versionadded:: 4.1
+    Output sections were introduced in Symfony 4.1.
+
+The regular console output can be divided into multiple independent regions
+called "output sections". Create one or more of these sections when you need to
+clear and overwrite the output information.
+
+Sections are created with the
+:method:`Symfony\\Component\\Console\\Output\\ConsoleOutput::section` method,
+which returns an instance of
+:class:`Symfony\\Component\\Console\\Output\\ConsoleSectionOutput`::
+
+    class MyCommand extends Command
+    {
+        protected function execute(InputInterface $input, OutputInterface $output)
+        {
+            $section1 = $output->section();
+            $section2 = $output->section();
+            $section1->writeln('Hello');
+            $section2->writeln('World!');
+            // Output displays "Hello\nWorld!\n"
+
+            // overwrite() replaces all the existing section contents with the given content
+            $section1->overwrite('Goodbye');
+            // Output now displays "Goodbye\nWorld!\n"
+
+            // clear() deletes all the section contents...
+            $section2->clear();
+            // Output now displays "Goodbye\n"
+
+            // ...but you can also delete a given number of lines
+            // (this example deletes the last two lines of the section)
+            $section1->clear(2);
+            // Output is now completely empty!
+        }
+    }
+
+.. note::
+
+    A new line is appended automatically when displaying information in a section.
+
+Output sections let you manipulate the Console output in advanced ways, such as
+:ref:`displaying multiple progress bars <console-multiple-progress-bars>` which
+are updated independently and :ref:`appending rows to tables <console-modify-rendered-tables>`
+that have already been rendered.
