How to change the rule color in cals table

Question

I make a table using cals package, I want to modify the width of the table using colwidths , when I rewrite the value in this code:\colwidths{{\dimexpr(\columnwidth)/34*4\relax}, the table widen to the right ,how could I make it widen to the left and right? And if I want to change the rule color to the RGB:221, 216, 195, how could I modify the code? Here is my code

\documentclass[a4paper, 11pt, UTF8]{ctexrep}

\usepackage{cals, caption}
\usepackage[svgnames]{xcolor}
\definecolor{st_table_blue}{RGB}{87, 142, 210}
\definecolor{gridcolor}{RGB}{221, 216, 195}
