实现代码

$section->addTextBreak(1);
$section->addText("Table with colspan and rowspan", $header);

$styleTable = array('borderSize' => 6, 'borderColor' => '999999');
$cellRowSpan = array('vMerge' => 'restart', 'valign' => 'center');
$cellRowContinue = array('vMerge' => 'continue');
$cellColSpan = array('gridSpan' => 2, 'valign' => 'center');
$cellHCentered = array('align' => 'center');
$cellVCentered = array('valign' => 'center');

$PHPWord->addTableStyle('Colspan Rowspan', $styleTable);
$table = $section->addTable('Colspan Rowspan');
$table->addRow();
$table->addCell(2000, $cellRowSpan)->addText('A', null, $cellHCentered);
$table->addCell(4000, $cellColSpan)->addText('B', null, $cellHCentered);
$table->addCell(2000, $cellRowSpan)->addText('E', null, $cellHCentered);
$table->addRow();
$table->addCell(null, $cellRowContinue);
$table->addCell(2000, $cellVCentered)->addText('C', null, $cellHCentered);
$table->addCell(2000, $cellVCentered)->addText('D', null, $cellHCentered);
$table->addCell(null, $cellRowContinue);
