Solution to add rowspan to addHTML() (PhpWord/Shared/Html.php)

[majeeed87]

update the code: phpoffice/phpword/src/PhpWord/Shared/Html.php

add this variable at the beginning of Html class:

protected static $rowIndex = 0;

protected static $columnIndex = 0;

protected static $rowSpanArray = [];

update parseTable method:

protected static function parseTable($node, $element, &$styles)
{
    $elementStyles = self::parseInlineStyle($node, $styles['table']);

    $newElement = $element->addTable($elementStyles);

    // Add style name from CSS Class
    if (isset($elementStyles['className'])) {
        $newElement->getStyle()->setStyleName($elementStyles['className']);
    }
	
	self::$rowIndex = 0;

    $attributes = $node->attributes;
    if ($attributes->getNamedItem('border')) {
        $border = (int) $attributes->getNamedItem('border')->nodeValue;
        $newElement->getStyle()->setBorderSize(Converter::pixelToTwip($border));
    }

    return $newElement;
}

update parseRow method:

protected static function parseRow($node, $element, &$styles)
{
    $rowStyles = self::parseInlineStyle($node, $styles['row']);
    if ($node->parentNode->nodeName == 'thead') {
        $rowStyles['tblHeader'] = true;
    }

    // set cell height to control row heights
    $height = $rowStyles['height'] ?? null;
    unset($rowStyles['height']); // would not apply
	
	self::$columnIndex = 0;
	self::$rowIndex = self::$rowIndex + 1;

    return $element->addRow($height, $rowStyles);
}

update parseCell method:

protected static function parseCell($node, $element, &$styles)
{
	$cellStyles = self::recursiveParseStylesInHierarchy($node, $styles['cell']);
	$vMergeStyle = self::recursiveParseStylesInHierarchy($node, $styles['cell']);
	self::$columnIndex = self::$columnIndex + 1;
	$search_items = ["rowIndex" => self::$rowIndex];
	$rowSpanCell = self::arraySearch(self::$rowSpanArray, $search_items);
	
	
	
	$colspan = $node->getAttribute('colspan');
	if (!empty($colspan)) {
		$cellStyles['gridSpan'] = $colspan - 0;
		self::$columnIndex = self::$columnIndex + $colspan - 1;
	}
	
	$rowspan = $node->getAttribute('rowspan');
	if (!empty($rowspan)) {
		$cellStyles['vMerge'] = 'restart';
		$gridSpan = 0;
		$colIndex = self::$columnIndex;
		if (!empty($colspan)){
			$gridSpan = $colspan;
			$colIndex = self::$columnIndex - $colspan + 1;
		}
		for ($x = 1; $x < $rowspan; $x++) {
		  array_push(self::$rowSpanArray, ['columnIndex'=>$colIndex, 'rowIndex'=>self::$rowIndex + $x, 'colspan'=>$gridSpan]);
		}
	}
	
	$currentColumnRowSpan = self::arraySearch($rowSpanCell, ["columnIndex" => self::$columnIndex]);

	// set cell width to control column widths
	$width = $cellStyles['width'] ?? null;
	unset($cellStyles['width']); // would not apply
	if (count($currentColumnRowSpan) > 0){
		$loop_check = self::$columnIndex;
	} else {
		$cell = $element->addCell($width, $cellStyles);
		$loop_check = self::$columnIndex + 1;
	}
	
	if (count($rowSpanCell) > 0) {
		unset($vMergeStyle['width']);
		foreach($rowSpanCell as $row) {
			if($row['columnIndex'] == $loop_check){
				$loop_check = $row['columnIndex'] + 1;
				
				if ($row['colspan'] > 0) {
					$vMergeStyle['gridSpan'] = $row['colspan'];
					self::$columnIndex = self::$columnIndex + $row['colspan'] + 1;
				} else {
					unset($vMergeStyle['gridSpan']);
					self::$columnIndex = self::$columnIndex + 1;
				}
				$vMergeStyle['vMerge'] = 'continue';
				$element->addCell(null, $vMergeStyle);
			}
		}
	}
	
	if (count($currentColumnRowSpan) > 0){
		$cell = $element->addCell($width, $cellStyles);
	}
	
	if (self::shouldAddTextRun($node)) {
		return $cell->addTextRun(self::filterOutNonInheritedStyles(self::parseInlineStyle($node, $styles['paragraph'])));
	}

	return $cell;
}

add arraySearch method:

// PHP program to search for multiple
// key=>value pairs in array

protected static function arraySearch($array, $search_list)
{
	// Create the result array
	$result = [];

	// Iterate over each array element
	foreach ($array as $key => $value) {
		// Iterate over each search condition
		foreach ($search_list as $k => $v) {
			// If the array element does not meet
			// the search condition then continue
			// to the next element
			if (!isset($value[$k]) || $value[$k] != $v) {
				// Skip two loops
				continue 2;
			}
		}

		// Append array element's key to the
		//result array
		$result[] = $value;
	}

	// Return result
	return $result;
}
