Column Width

Hi guys
Where can I set the column width? I found the view code, but I’m not quite understand: I need to add some argument to the columns? I’m not familiar with java, so I need help) Or maybe there is the easier way to do so


In the form: colSpan
Example :
<field name="subjectNum" colSpan="2" />
colSpan number of columns
The form uses responsive layout that adjusts according to the available screen size. The form is divided into 12 columns. The first 8 columns are used to place main panels and the rest 4 columns are used to place the sidebar panels. If sidebar panels are not provided the normal panels will occupy all the 12 columns.

In the grid: width
Example :
<field name="subjectNum" width="120" />
