如何使用 CSS 制作可滚动的表格

我的表有很多列，因此导致其宽度超跨。 我想让它水平滚动，以便它适合屏幕，看起来更整洁和有条理。我想 css 会隐藏属性溢出。但我不知道把我的 html 代码放在哪里。希望有人能帮忙。

<?php
$serverName = "kwe-PC'SQLEXPRESS";
$connectionInfo = array("Database" => "customerdb", "UID" => "dbadmin", "PWD" => "kwe");
$conn = sqlsrv_connect($serverName, $connectionInfo);
if ($conn === false) {
    die(print_r(sqlsrv_errors(), true));
}
//declare the SQL statement that will query the database
$query = "SELECT * FROM Customer_Details";
//execute the SQL query and return records
$result = sqlsrv_query($conn, $query)
        or die(print_r(sqlsrv_errors(), true));
//Show results in table
$o = '<table border=1 id="myTable">
