如何使用php更改excel单元格或列格式？

Question

<?php 
if($_POST) { 
//here i give test $result datas 
$result = array(array("Date"=>"2016-01-01","Time"=>"01:08:06","num"=>"","amount"=>"0.12"), array("Date"=>"2016-01-02","Time"=>"02:08:06","num"=>"1234567890","amount"=>"1.12"),array("Date"=>"2016-01-03","Time"=>"03:08:06","num"=>"1234567899","amount"=>"3.12") 
    ); 
    require_once "phpexcel/class.writeexcel_workbook.inc.php"; 
    require_once "phpexcel/class.writeexcel_worksheet.inc.php"; 
    $fname = tempnam("/tmp", "simple.xls"); 
    $workbook = &new writeexcel_workbook($fname); 

    $f_volume =& $workbook->addformat(); 
    //$f_volume->set_align('left'); 
    $f_volume->set_num_format('@'); 

    $gen =& $workbook->addformat(); 
    $gen->set_align('left'); 
    $gen->set_num_format('General'); 


    $dat =& $workbook->addformat(); 
    //$dat->set_align('left'); 
    $dat->set_num_format('DD/MM/YYYY'); 

    $inv_ref =& $workbook->addformat(); 
    $inv_ref->set_num_format('YYYY-MM-DD HH:MM:SS'); 

    $setup =& $workbook->addformat(); 
    $setup->set_align('left'); 
    $setup->set_num_format('#,###.00#'); 

    $tax =& $workbook->addformat(); 
    $tax->set_align('left'); 
    $tax->set_num_format('0.###%'); 

    $worksheet = &$workbook->addworksheet("My Report"); 

    $worksheet->write_string(0,0,'Date'); 
    $worksheet->write_string(0,1,'Time'); 
    $worksheet->write_string(0,2,'Dialled'); 
    $worksheet->write_string(0,3,'Rate'); 


    $worksheet->set_column(0,0,10,$dat); 
    $worksheet->set_column(0,1,10,$f_volume); 
    $worksheet->set_column(0,2,20,$f_volume); 
    $worksheet->set_column(0,3,10,$f_volume); 



    $j=1; 
    $unitTotal = 0; 
    $totalTotal = 0; 
    if(count($result) > 0) { 
     foreach($result as $outKey=>$rr){ 
      $worksheet->write($j,0,date("d/m/Y",strtotime($rr['Date']))); 
      $worksheet->write($j,1,$rr['Time']); 
      $worksheet->write($j,2,$rr['Dialled']); 
      $worksheet->write($j,3,$rr['Rate']); 
     } 
    } 

    $workbook->close(); 

    //header("Content-Type: application/x-msexcel; charset=UTF-8"); 
    header("Content-Type: application/x-msexcel; name=Calls Report.xls"); 
    header("Content-Disposition: inline; filename=Calls Report.xls"); 
    $fh=fopen($fname, "rb"); 
    fpassthru($fh); 
    unlink($fname); 
} 
?> 

我上面提到的代码都用来生成“我的报告”创先争优和它运作良好，问题是以后打开Excel右键单击在细胞>设置单元格格式 那么它显示的文本格式，但我需要证明，如果我选择日期然后格式是日期，如果时间然后格式是时间，如果它的数量然后格式是货币，我已经使用“$ dat”在这里设置日期格式，但它不工作。

从库文件，下载从GitHub库...

$objPHPExcel->getActiveSheet()->getStyle('A6') 
    ->getNumberFormat() 
    ->setFormatCode(
     PHPExcel_Style_NumberFormat::FORMAT_DATE_DATETIME 
    );
