我有这个带有 th 元素的标记，其中 text-overflow: ellipsis;溢出:隐藏；空白:nowrap;.
此外，td 和 th 设置为 display: block。
当我在第 th 上放置类似 width: 130px 的内容时，文本将显示省略号，否则不会。
我不知道还要在代码中添加什么，所以我只会发布我到目前为止所拥有的内容:
table {
display: flex;
overflow: hidden;
}
thead {
display: flex;
flex-shrink: 0;
width: 30%;
}
tbody {
display: flex;
position: relative;
width: 70%;
overflow-x: auto;
}
tr {
display: flex;
flex-direction: column;
min-width: 100%;
flex-shrink: 0;
}
td,
th {
display: block;
font-size: 13pt;
border: 1px solid black;
}
td {
border-left: 0;
}
th {
background-color: DarkSlateBlue;
font-weight: bold;
color: white;
text-overflow: ellipsis;
overflow: hidden;
white-space: nowrap;
}
th:not(:last-child),
td:not(:last-child) {
border-bottom: 0;

</table>最佳答案
tr 上的“flex-shrink”属性需要设置为 1，否则它只会从表中流出到下一个表中。默认值为 1，它告诉显示缩小 x 框中其他元素的值，因为只有一项将填充该框。
