Matrix form cell width

The emergency contact matrix "contact number" column width, I added last two row, but the column width is different from previous two row. Your people helped to change the width previously. 

Is there a easy way for us to change the width? 

I remember I could change the width before, but now I could not.

If you want to give the same width to each cell in the matrix "Emergency Contacts fore resident 2 (Please do not list the same as resident 1)", then inject this custom CSS code: http://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes 

#id_43 table.form-matrix-table input{

width: 200px !important;

}
