How can I increase column width of Input Table answer fields?

I need to have broad spaces in Input Table answer fields, how do I do that?

Inject the following code to increase the width:

table.form-matrix-table input{

width: 100px !important;

}

Let us know if you need more help.

Thank You for your help.

I just need to widen first and last column, the one with post address n comments. Can I do that?

This 100px is good for middle columns but I need the first and last column to be around 250px

Please remove the previous code I provided, and use the following code to make the first and last column 250px, and the middle columns 100px:

table.form-matrix-table input{

width: 100px;

}

.form-matrix-table td:nth-of-type(1) input{

width: 250px !important;

}

.form-matrix-table td:nth-of-type(7) input{

width: 250px !important;

}
