javascript A function to automatically wrap text with a custom length_javascript skills

In the process of making web pages, many friends always find that sometimes some English words will stretch out the original tables and cause deformation. Although you can use style="table-layout:fixed;word-wrap:break-word;word-break :break-all" to solve this problem, but sometimes it will cause the content to be displayed incompletely and be hidden, and the automatic line wrapping effect will not be achieved.

So I wanted to write a function like this to fix this defect. This function is very simple, but here I just provide an idea to solve this problem.

function fnAddBr(id, iPerLineLen){.....}
id is the id of the text block to be modified, iPerLineLen is the length of each line
nbsp;HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

The content I added when making the web page always made the table very wide horizontally after generating the web page, which was ugly;
I added
style="table-layout:fixed;word-wrap: break-word;word-break:break-all"

After this code, the table will not be stretched wide, but the content will not be fully displayed. Only the content with the same width as the table will be displayed, and the other content will be displayed. Blocked or filtered out.
Mine is in Chinese characters, does it matter?

Is there any way to automatically change the text in the table to a new line when it reaches a certain number of words? Or it can wrap lines without making the table too large, and without omitting content!
