Wordpress: Is there a way to adjust the Column Width for the Post table?

Question

None of the suggested topics about width concern WordPress. What I need is a way to adjust the width of the Posts table which comes up when Posts is selected (Title Author Categories, etc.) I've looked in Appearance/Edit at every .php Template and can't find anything relating to this. I'm sure I've missed something. Also, I have no immediate need for the "Date" and "Tags" columns. Can I either delete these or least hide them?

Thanks, Mike Carter

You can do this by creating a tiny plugin and activating it:

<?php
/*
Plugin Name: hidey
*/

add_action('admin_head', 'hidey_admin_head');

function hidey_admin_head() {
    echo '<style type="text/css">';
    echo '.column-date { display: none }';
    echo '.column-tags { display: none }';
    echo '.column-author { width:30px !important; overflow:hidden }';
    echo '.column-categories { width:30px !important; overflow:hidden }';
    echo '.column-title a { font-size:30px !important }';
    echo '</style>';
}
?>

Obviously, make your CSS adjustments as needed.
