嘿，我这里有个代码：

if ( !function_exists(\'AddThumbColumn\') && function_exists(\'add_theme_support\') ) {
    // for post and page
    add_theme_support(\'post-thumbnails\', array( \'post\', \'page\' ) );

    function AddThumbColumn($cols) {
        $cols[\'thumbnail\'] = __(\'Header Images\');
        return $cols;
    }

    function AddThumbValue($column_name, $post_id) {
        echo \'Header Image data here\';
    }

    add_filter( \'manage_pages_columns\', \'AddThumbColumn\' );
    add_action( \'manage_pages_custom_column\', \'AddThumbValue\', 10, 2 );

    function AddThumbColumn2($cols) {
        $cols[\'cssColor\'] = __(\'CSS Color\');
        return $cols;
    }

    function AddThumbValue2($column_name, $post_id) {
        //code goes here for second column      
    }

    add_filter( \'manage_pages_columns\', \'AddThumbColumn2\' );
    add_action( \'manage_pages_custom_column\', \'AddThumbValue2\', 10, 2 );
}

这适用于创建两个单独的列（标题图像，CSS颜色），但它似乎以CSS颜色复制标题图像中的数据。。？

为了让每一列都有自己的数据，我遗漏了什么？

add_action( \'manage_pages_custom_column\', \'AddColumnValue\', 10, 2 );

function AddColumnValue( $column_name, $post_id ) {
    if( \'thumbnail\' == $column_name ):
        echo \'Header Image data here\';
    elseif( \'cssColor\' == $column_name ):
        //code goes here for second column
    endif;
}
