Change width of column in configurable list

Hi,

It seems not possible to change the width of a column in the configurable list. (type = number)

I tried to change it in the CSS, but it doesn't work!

Can you please help me?

This seems to be due to the fact that there's already another piece of code affecting the field's width, to override that code you could add  "!important" to the code you injected, example:

td.col4 input {

    width: 93px !important;

}

Do note that "col4" will change based on the column number where the field is placed in. Also, the code needs to be injected in the widgets area: 

Hope this helps.
