元素不水平居中，图标不显示（css）

Question

我无法找出为什么text1不会水平居中以及为什么图标不会出现（我只有一个黑点而不是蓝色图标和 圆圈）。

<div id="texte_services">     
text1
</div>
  <div class="flex-container">
<div class="row">
    <div class="column">
        <p class="contenu">
            <img src="../Images/screen.png" alt="screen">
        </p>
    </div>
</div>                  
<table>
    <tr>
        <td>
            <div class="bullet">
            </div>
           <span class="blueText"><i class="fa fa-line-chart fa-lg"></i>
           </span>
            <span class="bluePoint">&bull;
            </span>
            <span class="titleText">
            </span>
        </td>
        <td>
            <h3>UX design
            </h3>
            <p>text2
            </p>   
        </td>
    </tr>               
    <tr>
        <td>
            <div class="bullet">
            </div>
           <span class="blueText"><i class="fa fa-line-chart fa-lg"></i>
           </span>
            <span class="bluePoint">&bull;
            </span>
            <span class="titleText">

        </td>
        <td>
            <h3>UX design
