我想根据父表格标题扩展内部表格单元格宽度 我试过了，但是我如何根据父标题单元格给出内部表格单元格宽度。
我用 boottrap 尝试了什么
<div class="table-responsive">
<table class="table table-sm table-bordered block-table">
<thead>
<th>Sr.</th>
<th>Product</th>
<th>Unit</th>
<th style="width: 15%">Serial Number</th>
<th>Date</th>
<th>Mac. Address</th>
<th>Batch No.</th>
<th>Qty</th>
<th>Std Pkg</th>
<th>Start Range</th>
<!-- <th>Assigned Quantity</th> -->
</thead>
<tbody>
<ng-container *ngFor="let inventory of inventoryList;let i=index">
<tr style="cursor: pointer;" (click)="toggleProductEntryTable(i)">
<td>{{i + 1}} </td>
<td> {{inventory?.displayString}} </td>
<td>{{inventory?.uomString}} </td>
<td colspan="7" style="padding: 0px">
<tbody>
<tr style="display: table-header-group" *ngFor="let productEntry of inventory.inventories;let proEnt=index">
<td style="display: table-cell;min-width: 160px"> {{productEntry?.subDetail?.serialNo}} </td>
<td style="display: table-cell;"> {{productEntry?.inventory?.date}} </td>
<td style="display: table-cell;"> {{productEntry?.subDetail?.macAddress}} </td>
<td style="display: table-cell;"> {{productEntry?.subDetail?.batchNo}} </td>
<td style="display: table-cell;"> {{productEntry?.checkoutDetail?.consumed - productEntry?.checkoutDetail?.assignedCount}} </td>
<td style="display: table-cell;"> {{productEntry?.subDetail?.standardPackingQuntity}}</td>
<td style="display: table-cell;"> {{productEntry?.checkoutDetail?.startRange}} </td>
<td style="display: table-cell;"> {{productEntry?.checkoutDetail?.endRange}} </td>
</tr>
</tbody>
</td>
</tr>
</ng-container>
</tbody>
</table>
</div>
.block-table {
display: table;
overflow-x: scroll;
max-height: 448px;
margin-bottom: 0px;
}
最佳答案
将 colspan="2"添加到您希望它跨越的列数(在您的情况下看起来像 10)
<!DOCTYPE html>
<html>
<head>
<style>
table,
th,
td {
border: 1px solid black;
}
</style>
</head>
<body>
<table>
<tr>
<th>Monthly Savings</th>
</tr>
<tr>
<td colspan="2">January</td>
</tr>
<tr>
<td colspan="2">February</td>
</tr>
</table>
