我试图在基于使用D3的那些单元格中的值的表格中的单元格附加SVG圆圈。使用D3.js将SVG元素附加到HTML表格单元格
这里就是我试图让：
.canvasBackground {
background-color: white
}
.table {
border-collapse: collapse;
border: #d0d4d5 solid 1px;
border-spacing: 0px;
font: normal 11px Georgia, 'Times New Roman', Times, serif;
letter-spacing: 1px;
line-height: 14px;
padding: 5px;
width: 100%
}
.headerStyle {
vertical-align: middle;
}
.headerRowStyle {
background-color: #fff;
border-bottom: 3px solid #ccc;
color: #4078a9;
font-size: 14px;
height: 48px;
line-height: 14px;
padding: 10px 5px 5px 5px
}
.headerCellStyle {
border-left: 1px solid #d0d4d5;
}
.tableBodyStyle {
text-align: left;
vertical-align: middle
}
.tableRowStyle {
background-color: #fff;
border-bottom: 1px solid #d0d4d5;
color: #565656;
padding: 5px 5px
}
.tableCellStyle {
border: 1px solid #d0d4d5;
}

<body>
<div class="canvasBackground">
\t <div class="tables"></div>
</body>从本质上讲，我想使用.append方法如果文本不包含颜色，例如“红色”，“黄色”或“绿色”，则在文本中附加<td>元素。如果文本包含这些颜色，我想使用相同的.append方法来追加一个子svg cirlce元素。但是当我使用.text方法时，我的svg元素消失了。
任何想法？
中超，@马克。谢谢！我不知道.filter方法。另外，感谢您清理代码。 – Tony
.filter超级有用，并且不限于d3！ – danimal
