1, adding excel library

Seen official documentation http://laravelacademy.org/post/2024.html

Chinese composer to use the mirror:

https://packagist.phpcomposer.com

There are two ways to enable this mirror service:

System Global Configuration: about to add information to the Composer configuration global configuration file config.jsonin. See "method"
Single project configuration: add configuration information to a project composer.jsonfile. See "Method II"

Method One: Modify composer global configuration file (the recommended way)

Open a command line window (windows users) or console (Linux, Mac users) and execute the following command:

composer config -g repo.packagist composer https://packagist.phpcomposer.com

Method two: modify the current project `composer.json`configuration file:

Open a command line window (windows users) or console (Linux, Mac user), into the root directory of your project (ie composer.jsonfile directory), execute the following command:

composer config repo.packagist composer https://packagist.phpcomposer.com

The above command will be in the current project of the composer.jsonend of the file is automatically added mirrored configuration information (you can also manually add your own):

"repositories": {
    "packagist": {
        "type": "composer",
        "url": "https://packagist.phpcomposer.com"
    }
}

Laravel project to composer.jsonthe configuration file, for example, after executing the command shown in the above-described (note that the last few lines) as follows:

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=5.5.9",
        "laravel/framework": "5.2.*"
    },
    "config": {
        "preferred-install": "dist"
    },
    "repositories": {
        "packagist": {
            "type": "composer",
            "url": "https://packagist.phpcomposer.com"
        }
    }
}

2, excel use

The official document: www.maatwebsite.nl/laravel-excel/docs/export

Official API there are some places insufficiency

Such as setting wrap

我们打开 vendor \ custom website \ excel \ src \ Size Site \ Excel \ Classes \ LaravelExcelWorksheet.php

加入方法：

public function setWrapText($styles)
{

    return    $this->getStyle($styles)->getAlignment()->setWrapText(true);;
}
使用如下：

$sheet->setWrapText('A1:K1',true);

设置列宽

打开vendor\maatwebsite\excel\src\Maatwebsite\Excel\Writers\LaravelExcelWriter.php

加入方法

public function setWeight($styles,$weight){
    return $this->excel->getActiveSheet()->getColumnDimension($styles)->setWidth($weight);
}

使用如下：

$excel->setWeight('B',17);

以上是举例说明自己添加一些方法，具体可以查找一些PHPexcel的方法实现然后实现到自己的代码中，其实Excel类就是对PHPexcel的一个封装
