我有一个动态表,其中的数据来自API。我正在生成表并使用JavaScript插入行。
一切正常,但问题出在样式上。
我的表行颜色被剥离(就像我们使用引导程序表条纹类一样),并且每行中的单元格都不相同。
有些有3个,有些有6个,有些4个,依此类推。如果单元格较少,它们将显示一些空白。
有什么办法可以给整行着色吗?这是一个例子。这是我的代码示例:
.table-striped th {
height: 45px;
background-color: #bfff00 !important;
color: #191919;
}
.table-striped td {
padding: 8px;
border: 2px solid #F6F6F6;
font-weight: bold;
}
.table-striped>tr:nth-child(n+1)>td {
background-color: #bababa;
}
.table-striped>tr:nth-child(n+2)>td {
background-color: #e8e7e6;
}
<div>
<table class="table-striped">
<tr>
<th>Header 1</th>
<th>Header 2</th>
<th>Header 3</th>
<th>Header 4</th>
<th>Header 5</th>
<th>Header 6</th>
<th>Header 7</th>
<th>Header 8</th>
</tr>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
</tr>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
<td>Cell 4</td>
<td>Cell 5</td>
<td>Cell 6</td>
<td>Cell 7</td>
<td>Cell 8</td>
</tr>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
<td>Cell 4</td>
<td>Cell 5</td>
</tr>
</table>
</div>

表格行仅与单元格数一样宽。
在没有整行时添加最后一个单元格,并适当地使用colspan
。
.table-striped th {
height: 45px;
background-color: #bfff00 !important;
color: #191919;
}
.table-striped td {
padding: 8px;
border: 2px solid #F6F6F6;
font-weight: bold;
}
.table-striped tr:nth-child(odd) {
background-color: #bababa;
}
.table-striped tr:nth-child(even) {
background-color: #e8e7e6;
}
<div>
<table class="table-striped">
<tr>
<th>Header 1</th>
<th>Header 2</th>
<th>Header 3</th>
<th>Header 4</th>
<th>Header 5</th>
<th>Header 6</th>
<th>Header 7</th>
<th>Header 8</th>
</tr>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
<td colspan="5"></td>
</tr>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
<td>Cell 4</td>
<td>Cell 5</td>
<td>Cell 6</td>
<td>Cell 7</td>
<td>Cell 8</td>
</tr>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
<td>Cell 4</td>
<td>Cell 5</td>
<td colspan="3"></td>
</tr>
</table>
</div>
MDN的注释:
应用于
<tr>
元素的任何样式都会影响其中的单元格 该行,除非被应用于这些单元格的样式所覆盖。
要特别注意它为单元格设置样式的事实,而不是行本身
编辑
从您的问题和评论中我们知道您正在使用javascript生成表。我们无法推断出如何执行此操作,但是如果您逐行生成表格,则应该能够查看是否已为该行生成的单元格数量等于th
细胞。如果不是,请添加一个差异为colspan
的单元格。如果无法执行此操作,则可以在创建表后 。
这是一个粗糙的方法
function addColspan(table) {
//Assume number of th are our max cells per row
var maxCells = table.querySelectorAll("th").length;
//Get all rows but the first
var rows = table.querySelectorAll("tr:nth-child(n+2)");
for(var i = 0; i < rows.length; i++){
//Get how many cells we have
var cellCount = rows[i].querySelectorAll("td").length;
//If we don't have enough cells
if(cellCount < maxCells) {
//Add one with the appropriate colspan
rows[i].innerHTML += "<td colspan='" + (maxCells - cellCount) + "'></td>";
}
}
}
//Run after table is generated
addColspan(document.querySelector(".table-striped"));
.table-striped th {
height: 45px;
background-color: #bfff00 !important;
color: #191919;
}
.table-striped td {
padding: 8px;
border: 2px solid #F6F6F6;
font-weight: bold;
}
.table-striped tr:nth-child(odd) {
background-color: #bababa;
}
.table-striped tr:nth-child(even) {
background-color: #e8e7e6;
}
<div>
<table class="table-striped">

<th>Header 3</th>
<th>Header 4</th>
<th>Header 5</th>

<th>Header 7</th>

您可以在CSS中使用even
和odd
属性。
检查一下
.table-striped th {
height: 45px;
background-color: #bfff00 !important;
color: #191919;
}
.table-striped td {
padding: 8px;
border: 2px solid #F6F6F6;
font-weight: bold;
}
.table-striped tr:nth-child(odd) td {
background-color: #bababa;
}
.table-striped tr:nth-child(even) td {
background-color: #e8e7e6;
}
<div>
<table class="table-striped">
<tr>
<th>Header 1</th>
<th>Header 2</th>
<th>Header 3</th>
<th>Header 4</th>
<th>Header 5</th>
<th>Header 6</th>
<th>Header 7</th>
<th>Header 8</th>
</tr>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
</tr>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
<td>Cell 4</td>
<td>Cell 5</td>
<td>Cell 6</td>
<td>Cell 7</td>
<td>Cell 8</td>
</tr>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
<td>Cell 4</td>
<td>Cell 5</td>
</tr>
</table>
</div>
评论后更新了答案。您需要将alteast留空以突出显示完整的行。
.table-striped th {
height: 45px;
background-color: #bfff00 !important;
color: #191919;
}
.table-striped td {
padding: 8px;
border: 2px solid #F6F6F6;
font-weight: bold;
}
.table-striped tr:nth-child(odd) td {
background-color: #bababa;
}
.table-striped tr:nth-child(even) td {
background-color: #e8e7e6;
}
<div>
<table class="table-striped">
<tr>
<th>Header 1</th>
<th>Header 2</th>
<th>Header 3</th>
<th>Header 4</th>
<th>Header 5</th>
<th>Header 6</th>
<th>Header 7</th>
<th>Header 8</th>

尝试为您的行指定一个ID。然后,您应该能够在CSS代码中访问整行。
