我对 HTML 和 CSS 还很陌生，我尝试制作一个响应式的全屏表格，但由于它我无法使用导航栏。这可能是因为位置：绝对属性，但我不知道如何在不破坏它的情况下更改它。如果我更改position：absolute属性或删除它，则表将完全损坏。var table = document.getElementById("table");var w = window.innerWidth;var h = window.innerHeight;var wsquare = 30, hsquare = 30;var m = w / wsquare, n = h / hsquare;for(var i = 0; i < n - 1; i++) { var row = table.insertRow(i); for(var j = 0; j < m - 1; j++) { var cell1 = row.insertCell(j); }}th, table, td{ border: 1px solid black; border-collapse: collapse;}table { position: absolute; left: 0; top: 0; right: 0; bottom: 0; width: 100%; height: 100%;}<!DOCTYPE html><html dir="ltr"> <head> <meta charset="utf-8"> <title>PathFinding</title> <link rel="stylesheet" type="text/css" href="style.css"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css"> </head> <body> <nav class="navbar navbar-inverse"> <div class="container-fluid"> <div class="navbar-header"> <a class="navbar-brand" href="#">Name</a> </div> <ul class="nav navbar-nav"> <li class="active"><a href="#">Home</a></li> <li><a href="#">Page 1</a></li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> </div> </nav> <div class="table"> <table id= "table"> </table> </div> <script type="text/javascript" src="script.js"></script> </body></html>

我做了一些编辑，现在你的导航栏工作正常：
如果你想使用绝对定位，只需添加position:relative; 导航栏和更高的 **z-index*
var table = document.getElementById("table");
var w = window.innerWidth;
var h = window.innerHeight;
var wsquare = 30, hsquare = 30;
var m = w / wsquare, n = h / hsquare;
for(var i = 0; i < n - 1; i++) {
var row = table.insertRow(i);
for(var j = 0; j < m - 1; j++) {
var cell1 = row.insertCell(j);
}
}
nav {
position:relative;
z-index: 2;
}
table {
position: absolute;
left: 0;
top: 0;
right: 0;
bottom: 0;
width: 100%;
height: 100%;
}
th, table, td{
border: 1px solid black;
border-collapse: collapse;
}
