Alternate row color in rc-table only works on hover！

[zwjsoft]

I'm using the rc-table component to display a table with alternate row colors. However, the background color of even rows only takes effect when I hover over them with the mouse. I've tried adding the CSS code table tr:nth-child(even) { background: #CCE8E8; }, but it doesn't seem to be working as expected.、 Can someone help me figure out why the even rows' background color only works on hover? Thank you! CSS： .rc-table table tr:nth-child(even){background:#CCE8E8!important;}
