Add ability to add row in a loop to existing table

[Copilot]

Implementation Plan for Incremental Table Row Display

• Analyze codebase structure and understand Table class implementation
• Identify existing test infrastructure (PHPUnit tests)
• Run existing tests to establish baseline
• Add resetRows() method to clear only rows (not headers/footers)
• Add displayRow() method to display single row without headers/borders
• Add internal state tracking to manage whether table has been displayed
• Create PHPUnit tests for new functionality
• Validate changes with existing and new tests
• Run full test suite (lint, phpcs, phpstan, phpunit)
• Fix border cache issue in Ascii renderer
• Update example to demonstrate proper usage
• Remove duplicate bottom border for cleaner incremental display
• Remove example file per review feedback
• Address code review feedback (unused property, proper cleanup, assignment in args)

This section details on the original issue you should resolve

<issue_title>Add ability to add row in a loop to existing already-rendered table</issue_title>
<issue_description>## Feature Request

• Yes, I reviewed the contribution guidelines.

Describe your use case and the problem you are facing

I want to "register" an empty table, and then later in a loop using table reference ($table) add rows.

Right now if I register a table, call the display() method to render it, and then later call the

$table->addRow(); $table->display();

it will render the whole table again - with headers and previously added rows.

Describe the solution you'd like

I think separating resetTable() method into individual methods for header, rows, footer is needed.

So I should be able to either do this:

$table->setHeaders(); $table->display(); foreach ($rowsas$row){$table->resetRows(); $table->addRow($row); $table->display()}

or something like this:

$table->setHeaders(); $table->display(); foreach ($rowsas$row){$table->displayRow($row)}

Also, because header is a mandatory table data, displaying a new row should not render the top border but render the bottom row.</issue_description>

Comments on the Issue (you are @copilot in this section)

@danielbachhuber Seems fine to me, as long as there aren't any backcompat breaks. Feel free to submit a PR if you'd like.

Changes:

• Added resetRows() method to clear only row data while preserving headers and footers
• Added displayRow() method to display individual rows without headers or top borders
• Fixed border rendering issues in the Ascii renderer to prevent duplicate borders
