Characters do not support common css styles in Big Tables _ experience exchange

Enter characters in a table with fixed width. If all the characters entered are English characters, the more characters entered, the table will be extended gradually, this problem can be avoided unless you press enter to wrap the line. If the input is a Chinese character, this problem does not exist. I have encountered such a problem now. Could you tell me if there is any solution to this problem? Whether it is purely Chinese or English, or mixed Chinese and English characters, are tables not extended? These are the related css:
Table-layput: fixed; word-wrap: break-wrod; word-break: break-all;
