我似乎无法在我的 Bootstrap 表格行中垂直对齐所有不同类型的元素。我希望“选择”下拉菜单、描述文本和按钮都显示为垂直居中。我需要做什么来解决这个问题?

what it looks like

代码如下:

<!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

<title>testing...</title>
<style>
td {
height: 1em;
vertical-align: middle;
}
</style>
</head>
<body>
<div style="margin-left: 0px">
<table class="table table-striped table-hover">
<colgroup>
<col span="1" style="width: 4em">
<col span="1" style="width: 15em">
<col span="1" style="width: 4em">
</colgroup>
<tbody>
<tr scope="row"><td>
<select class="form-control" id="qty">
<option>0</option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
</td><td>Apples</td><td>10lb</td><td><button type="button" class="btn btn-primary btn-sm">Add</button></td></tr>
</table>

最佳答案

设置vertical-align:middle为.table类表格数据。

    .table td {
height: 1em;
vertical-align: middle;
}

  <!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

<title>testing...</title>
<style>
.table td {
height: 1em;
vertical-align: middle;
}
</style>
</head>
<body>
<div style="margin-left: 0px">
<table class="table table-striped table-hover">
<colgroup>
<col span="1" style="width: 4em">
<col span="1" style="width: 15em">

<tbody>
<tr scope="row">

<select class="form-control" id="qty">

<option>2</option>
<option>3</option>

<td>Apples</td>
<td>10lb</td>
<td><button type="button" class="btn btn-primary btn-sm">Add</button></td>
</tr>
</table></div>

解决方案 2:您还可以使用 !important 来覆盖 css 属性。

td {
height: 1em;
vertical-align: middle !important;
}

<!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
<title>testing...</title>
<style>
td {
height: 1em;
vertical-align: middle !important;
}
</style>
</head>

<body>
<div style="margin-left: 0px">
<table class="table table-striped table-hover">
<colgroup>
<col span="1" style="width: 4em">
<col span="1" style="width: 15em">
<col span="1" style="width: 4em">
</colgroup>
<tbody>
<tr scope="row">
<td>
<select class="form-control" id="qty">
<option>0</option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
</td>
<td>Apples</td>
<td>10lb</td>
<td><button type="button" class="btn btn-primary btn-sm">Add</button></td>
</tr>
</table>
</div>

解决方案 3:使用 Bootstrap 将 align-middle 类添加到 td。

<tr scope="row">
<td class="align-middle">
<select class="form-control" id="qty">
<option>0</option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
</td>
<td class="align-middle">Apples</td>
<td class="align-middle">10lb</td>
<td class="align-middle"><button type="button" class="btn btn-primary btn-sm">Add</button></td>
</tr>

<!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

<title>testing...</title>
<style>
td {
height: 1em;
}
</style>
</head>
<body>
<div style="margin-left: 0px">
<table class="table table-striped table-hover">
<colgroup>
<col span="1" style="width: 4em">
<col span="1" style="width: 15em">
<col span="1" style="width: 4em">
</colgroup>
<tbody>
<tr scope="row">
<td class="align-middle">
<select class="form-control" id="qty">
<option>0</option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
</td>
<td class="align-middle">Apples</td>
<td class="align-middle">10lb</td>
<td class="align-middle"><button type="button" class="btn btn-primary btn-sm">Add</button></td>
</tr>
</table>
</div>
