.form-matrix-values .form-textbox {

width: 100px !important;

}/* 2nd Column */

.form-matrix-row-headers +

.form-matrix-values +

.form-matrix-values .form-textbox {

width: 100px !important;

}/* 3rd Column */

.form-matrix-row-headers +

.form-matrix-values .form-textbox {

width: 100px !important;

}/* 4th Column */
