Table header wraps to 2 lines

I am very new to wordpress/tablepress and am struggling trying to get the Intermediate Table header to go on one line and be centered.

I have been playing around with the width pixels but it only is increasing the width column and the text is still on two lines?

.tablepress-id-64 .column-1 {
	width: 400px;
	text-align: center;
}

Very much would appreciate your help!

Thank you in advance.
