如果想在左側導覽面板建立新的報表，只顯示來源/媒介是桌上型電腦使用者的詳細資料，該使用哪種新的報表範本？

The "Traffic acquisition" report template is the correct choice because it focuses on how users arrive at your site, including source/medium data. This template allows you to customize the report to filter for desktop users specifically, providing the detailed information you need about their acquisition. "Demographics details" focuses on user characteristics like age and gender. "Landing page" reports on the first page users see, not their acquisition source. "Tech details" focuses on devices, browsers, and operating systems, which is related but doesn't directly provide the source/medium breakdown you're looking for alongside desktop user data in a single, customizable report template.
