如何更改以PDF格式保存的表格的列宽我有这个代码

<?php
   $data_provider = $model->viewEmployees($search, $from, $to);
   $data_provider->pagination = false;   

$this->widget('ext.pdfGrid.EPDFGridPortrait', array(
        'id' => 'employee-pdf',
        'fileName' => 'Employees',
        'dataProvider' => $data_provider,
        'columns' => array(
            array('name' => '#', 'value'=>'$row+1',  
                  'htmlOptions' => array('style'=>'width:30px')
                 ),

            array('name' => 'ID Number','value' => '$data->company_id', 
                  'htmlOptions'=>array('style'=>'width:150px'),                      
                 ),

            array('name' => 'Name', 'header' => 'Name', 'value' => '$data->getNameWithMiddleInitial()', 
                  'htmlOptions' => array('style'=>'width:200px'),
                  ),

            array('name' => 'Date Employed', 'value' => '$data->date_employed' ,
                  'htmlOptions'=>array('style'=>'width:200px'),
                  ),            
        ),
        'config' => array(
            'subTitle' => 'List of Employees',
            'headerDetails' => true,
            'showLogo' => true,
            'colAligns' => array('C', 'L', 'C'),
        ),
    ));

  ?>

我已尝试在我的代码中使用此'htmlOptions' => array('style'=>'width:30px'),但似乎无效。请帮忙。

似乎它只是调用EPDFGridPortrait.php这是代码..

抱歉长码。我只是困惑为什么这一行

'htmlOptions' => array('style'=>'width:30px'),

无法正常工作..

Answer 1

我已经弄清楚了列的宽度是如何工作的。

我在'config'数组

中添加了这一行

'colWidths' => array(10, 30, 85, 65),

给了我

'config' => array(
            //'title' => 'Sprobe Inc. Information Management System',
            'subTitle' => 'List of Employees',
            'header' => false,
            'showLogo' => true,
            'colAligns' => array('C', 'C', 'L',/* 'L',*/ 'C'),
            'colWidths' => array(10, 30, 85, 65),
        ),

colWidths操纵每个列的宽度，它依赖于我的EPDFGridPortrait.php函数_calcWidths中的参数

更改列宽Yii
