如何在PHPExcel合并单元格中居文本

Question

如何将文本中心"测试"？

这是我的代码:

<?php
    /** Error reporting */
    error_reporting(E_ALL);
    ini_set('display_errors', TRUE);
    ini_set('display_startup_errors', TRUE);
    date_default_timezone_set('Europe/London');

    /** Include PHPExcel */
    require_once '../Classes/PHPExcel.php';

    $objPHPExcel = new PHPExcel();
    $sheet = $objPHPExcel->getActiveSheet();
    $sheet->setCellValueByColumnAndRow(0, 1, "test");
    $sheet->mergeCells('A1:B1');
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
    $objWriter->save("test.xlsx");

Answer 1

如果你只想对齐这个单元格,你可以这样做:

    $style = array(
        'alignment' => array(
            'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
        )
    );

    $sheet->getStyle("A1:B1")->applyFromArray($style);

但是,如果要将此样式应用于所有单元格,请尝试以下操作:

    $style = array(
        'alignment' => array(
            'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
        )
    );

    $sheet->getDefaultStyle()->applyFromArray($style);

<?php
    /** Error reporting */
    error_reporting(E_ALL);
    ini_set('display_errors', TRUE);
    ini_set('display_startup_errors', TRUE);
    date_default_timezone_set('Europe/London');

    /** Include PHPExcel */
    require_once '../Classes/PHPExcel.php';

    $objPHPExcel = new PHPExcel();
    $sheet = $objPHPExcel->getActiveSheet();
    $sheet->setCellValueByColumnAndRow(0, 1, "test");
    $sheet->mergeCells('A1:B1');
    $sheet->getActiveSheet()->getStyle('A1:B1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
    $objWriter->save("test.xlsx");
?>

Answer 3

解决方案是通过此函数设置单元格样式:

$sheet->getStyle('A1')->getAlignment()->applyFromArray(
    array('horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,)
);

完整代码

<?php
/** Error reporting */
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');

/** Include PHPExcel */
require_once '../Classes/PHPExcel.php';

$objPHPExcel = new PHPExcel();
$sheet = $objPHPExcel->getActiveSheet();
$sheet->setCellValueByColumnAndRow(0, 1, "test");
$sheet->mergeCells('A1:B1');
$sheet->getStyle('A1')->getAlignment()->applyFromArray(
    array('horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,)
);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save("test.xlsx");

Answer 4

我们也可以使用这种方式设置垂直对齐

$style_cell = array(
   'alignment' => array(
       'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
       'vertical' => PHPExcel_Style_Alignment::VERTICAL_CENTER,
   ) 
); 

使用此单元格将垂直对齐设置为中间。
