我的CSS表有问题吗？

使用

空白的属性：normal或
断字：全部断字我认为它会起作用。
问题不在上面的代码片段中。当我测试它时，表中的句子像你预期的那样分布在多行上。我在Chrome和IE11上测试。。。仍然和上面的问题一样这工作完全像我想要的。。。谢谢你。作为澄清：单词break:break all；将打破所有字母，这意味着中断可能发生在词的中间。
.div-assump {
    float: left
}

.tbl-row-assump td:nth-child(1){
    vertical-align: middle
}

.tbl-row-assump td:nth-child(2) {
    background-color: red;
    max-width: 500px;
    word-wrap: break-word;
    text-wrap: normal;
    text-align: justify
}
