我正在尝试构建一个非常简单的数组,但不知何故它不起作用我认为它应该如何。这是一个例子:
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
}
</style>
</head>
<body>
<table width=100%>
<tr>
<th colspan="8">sigle row of 8 cols</th>
</tr>
<tr >
<td colspan="2">2 cols </td>
<td rowspan="3" colspan="6" > 6 cols</td>
</tr>
<tr>
<td colspan="2">2 cols</td>
</tr>
<tr>
<td colspan="2">2 cols</td>
</tr>
</table>
</body>
</html>
请帮我调试。 我希望几个月只占用2列,并且保存占用6列(其余的),但是,这不能按预期工作。我知道答案是微不足道的,但我找不到它。你能告诉我出了什么问题吗?

该表将有8列,但您已经有效地将其缩减为2.表格渲染算法将使事情尽可能高效。
通过添加额外的行,您可以看到正在发生的事情
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
}
</style>
</head>
<body>
<table width=100%>
<tr>
<th colspan="8">Monthly Savings</th>
</tr>
<tr >
<td colspan="2">January</td>
<td rowspan="3" colspan="6" >$30000</td>
</tr>
<tr>
<td colspan="2">February</td>
</tr>
<tr>
<td colspan="2">March</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
<td>5</td>
<td>6</td>
<td>7</td>
<td>8</td>
</tr>
</table>
</body>
</html>

你最好做的是为列分配宽度
table, th, td {
border: 1px solid black;
}
&#13;
<table width=100%>
<tr>
<th colspan="2">Monthly Savings</th>
</tr>
<tr >
<td style="width:33%">January</td>
<td rowspan="3" style="width:66%" >$30000</td>
</tr>
<tr>
<td>February</td>
</tr>
<tr>
<td>March</td>
</tr>
</table>
&#13;
答案 1 :(得分:1)
因为您添加heading in single <th>
所以使ID不同
<th colspan="2">Monthly</th>
<th colspan="6">Savings</th>
因此它会显示2 for month
和6 for saving
<!DOCTYPE html>
<html>
<head>
<style>
table,
th,
td {
border: 1px solid black;
}
</style>
</head>
<body>
<table width=100%>
<tr>
<th colspan="2">Monthly</th>
<th colspan="6">Savings</th>
</tr>
<tr>
<td colspan="2">January</td>
<td rowspan="3" colspan="6">$30000</td>
</tr>
<tr>
<td colspan="2">February</td>
</tr>
<tr>
<td colspan="2">March</td>
</tr>
</table>
</body>
</html>
