如何删除td标签中的空白？

Question

我有一个 html 表，我用复杂的逻辑填写 php。 有 4 个 foreach 循环来填充数据。

现在这工作正常，但通过循环我在我的元素中得到了一些空白。 浏览器可以正常显示，但是一要导出成pdf，就有点问题了。

任何人都知道如何消除这些空格。查看图片以获得更多说明：

这是我的变量的代码，我回显的变量没有任何空格。如果发出 echo "test"; 也会出现问题：

<div id="autoload-content"> 

    <table class="tg" >
      <thead>
          <tr>
            <th></th>
            <th>Montag</th>
            <th>Dienstag</th>
            <th>Mittwoch</th>
            <th>Donnerstag</th>
            <th>Freitag</th>
          </tr>
      </thead>
      <tbody>

    <?php
        $arrNoDoubleEntries = array();
        $totalFactorMo = 0;
        $stackIrregular = array();

        //displays all the different presencetypes
        foreach ($types as &$value) {
        ?>    
         <tr>
            <td><?php echo ($value->Name);?></td>

            <td>
            <?php //all Monday Childs

在您的情况下，尝试连接 html，然后将其显示为

<?php //all Monday Childs 
    $html = '';
        if ($value->Name == "Total"){
            $html .= ($totalFactorMo);
        }else{
            $childrenMonday = (Children::LoadPresence(1, $groupId));
                foreach ($childrenMonday as &$child) {
                        foreach ($irregularPresence as &$irrugPrese){

                            if (($child->id == $irrugPrese->child_id) && ($monday >= $irrugPrese->datefrom) && ($monday <= $irrugPrese->dateto)){
                                if ($irrugPrese->away == 1 && ($value->id == $child->presencetype)){                                
                                        $html .=("<s>".$child->fullName . " " . $child->factor."</s>");
                                        $html .= "<br />";
                                        array_push($stackIrregular, $child->id);
                                }

                                else{   

                                        if (($value->id == $irrugPrese->presencetype_id) AND (!(in_array($child->fullName + $irrugPrese->presencetype_id, $arrNoDoubleEntries)))){
                                            $html .=("<u>".$child->fullName . " " . $child->factor."</u>");
                                            $html .= "<br />";
                                            array_push($arrNoDoubleEntries, $child->fullName + $irrugPrese->presencetype_id);
                                            $totalFactorMo = $totalFactorMo + $child->factor;
                                        }
                                }
                            }
                        }

                    if (!(in_array($child->id, $stackIrregular))) {
                        //prints the children which dont have some irregular Presences
                        if (!($child->presencetype == 1) && ($value->id == $child->presencetype)){
                            $html .= ($child->fullName . " " . $child->factor);
                            $html .= "<br />";
                            $totalFactorMo = $totalFactorMo + $child->factor;
                        }
                    }
                }
        }
        echo $html;

        ?>

Answer 2

您可以在显示在表格中之前从变量中修剪空格

$string = preg_replace('/\s+/', '', $string);

或

$string = str_replace(' ', '', $string);

Answer 3

在打印值之前去掉所有的空白。

EG：

function cleanSpaces($text)  
{
  $text = preg_replace('/(xC2xA0/| )','',$text); //remove  
  $text = preg_replace('/\s+/', '', $loop_variable_value); //remove whitespace
  return $text;
}
