composer require phpoffice/phpspreadsheet
PhpSpreadsheet提供了丰富的API接口，可以设置诸多单元格以及文档属性，包括样式、图片、日期、函数等等诸多应用，总之你想要什么样的Excel表格，PhpSpreadsheet都能做到
在使用phpoffice/phpspreadsheet的API接口前，确保引入了正确的文件并实例化
use PhpOffice\PhpSpreadsheet\Spreadsheet;//引入文件 $spreadsheet = new PhpOffice\PhpSpreadsheet\Spreadsheet();//创建一个新的excel文档 $sheet = $spreadsheet->getActiveSheet();//获取当前操作sheet的对象
$sheet->getStyle('A7:B7')->getFont()->setBold(true)->setName('Arial')
->setSize(10);//将A7至B7两单元格设置为粗体字，Arial字体，10号字
$sheet->getStyle('B1')->getFont()->setBold(true);//将B1单元格设置为粗体字$sheet->getStyle('A1')->getFont()->getColor()->setARGB(\PhpOffice\PhpSpreadsheet\Style\Color::COLOR_RED);//将A1单元格文字颜色设为红色$sheet->getColumnDimension('A')->setWidth(20);//将A列的宽度设为20(字符)
$sheet->getColumnDimension('B')->setAutoSize(true);//将B列的宽度设为自动宽度
$sheet->getDefaultColumnDimension()->setWidth(12);//设置默认列宽为12$sheet->getRowDimension('10')->setRowHeight(100);//将第十行的高度设为100pt
$sheet->getDefaultRowDimension()->setRowHeight(15);//设置默认行高为15$sheet->getStyle('A:D')->getAlignment()
->setVertical(\PhpOffice\PhpSpreadsheet\Style\Alignment::VERTICAL_CENTER) //设置垂直居中
->setHorizontal(\PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER) //设置水平居中
->setWrapText(true); //设置自动换行$sheet->mergeCells('A1:D2');//A1到D2合并为一个单元格$sheet->unmergeCells('A1:D2');//将合并后的单元格拆分。//样式变量
$style = [
//设置字体样式
'font' => [
'name' => 'Arial',
'bold' => true,
'italic' => false,
'underline' => Font::UNDERLINE_DOUBLE,
'strikethrough' => false,
'color' => [
'rgb' => '808080'
]
],
//设置边框线样式
'borders' => [
//allBorders所有的边框线样式
//左边框线
'bottom' => [
'borderStyle' => Border::BORDER_DASHDOT,
'color' => [
'rgb' => '808080'
]
],
//上边框线
'top' => [
'borderStyle' => Border::BORDER_DASHDOT,
'color' => [
'rgb' => '808080'
]
]
],
//对齐样式
'alignment' => [
'horizontal' => Alignment::HORIZONTAL_CENTER,
'vertical' => Alignment::VERTICAL_CENTER,
'wrapText' => true,
],
//是否使用前缀
'quotePrefix' => true
];
$sheet->getStyle('A1:D1')->applyFromArray($style);$sheet->setTitle('Hello');;//设置当前工作表标题。$sheet->getStyle('D2')->getNumberFormat()
->setFormatCode(\PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_TEXT);//将D2单元格的格式设为文本格式
$sheet->getStyle('A1:D2')->getNumberFormat()
->setFormatCode(\PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_TEXT);//将A1到D2的单元格设置为文本格式$sheet->getCell('A4')->setValue("hello\nworld");//将A4单元格的hello和world换行//将A2单元格内容设置blog并点击跳转https://www.wj0511.com
$sheet->setCellValue('A2', 'blog');
$sheet->getCell('A2')->getHyperlink()->setUrl('https://www.wj0511.com');常用函数有：总和(SUM)，最大数(MAX)，最小数(MIN)，平均值(AVERAGE)
$sheet->setCellValue('B5', '=SUM(B1:B4)');//将B5单元格的内容设为B1到B4的之和$spreadsheet->getProperties()
->setCreator("author") //作者
->setLastModifiedBy("last-author") //最后修改者
->setTitle("title") //标题
->setSubject("subject") //副标题
->setDescription("description") //描述
->setKeywords("keywords") //关键字
->setCategory("category"); //分类<?php
