Refer to the minimum width style on the internet, [html]/* minimum degree of attention */. min_width {min-width: 300px;/* sets max-width for IE */_ width: expression (document. body. clientWidth <300? "300px": "auto");} is written as follows: [html] <style>. ckblstEffect td {min-width: 80px; _ width: expression (document. body. clientWidth <80?

If you look at the expressions in the style carefully, you may feel wrong. Change to the following style. [Html] <style>. ckblstEffect td {min-width: 80px; width: expression (this. offsetWidth <80? "80px": "auto") ;}</style> In IE10, travel 4, and compatibility modes, the minimum width is displayed correctly. In addition to CheckBoxList, it can also be used for DIV and so on.
