我是新人，仍在學(xué)習(xí)：我已經(jīng)創(chuàng)建了 HTML 表格，但布局有問題。當(dāng)我復(fù)制表格時，它會弄亂我的布局，看看編號為 2 的表格，表格應(yīng)該看起來相同：第二個表格應(yīng)該看起來像表格編號 1var tbody = document.querySelector('tbody');var thscoped = document.querySelector('tbody .sem');var count = 0;for (var ch = tbody.firstChild; ch; ch = ch.nextSibling)? if (ch instanceof HTMLElement) count++;thscoped.setAttribute("rowspan", count);.sem {? border:1px solid red}有人能幫我解決這個問題嗎？

您剛剛在 Javascript 代碼中使用了第一個 tbody。讓我們試試這個。
var tbody = document.querySelectorAll('tbody');
tbody.forEach(function(bdy){
let thscoped = bdy.querySelector('.sem');
var count = 0;
for (var ch = bdy.firstChild; ch; ch = ch.nextSibling)
if (ch instanceof HTMLElement) count++;
thscoped.setAttribute("rowspan", count);
});
.sem {
border:1px solid red
}

您有兩個tbody元素，但var tbody = document.querySelector('tbody');只獲取第一個。您需要將它們?nèi)揩@取并循環(huán)遍歷它們。
