關於 Markdown 速查表
這份 Markdown 速查表把整套語法集中在一個可搜尋的頁面上：基本語法、清單、連結與圖片、程式碼與程式碼區塊、表格、引用與分隔線、GitHub 風格的擴充、跳脫與內嵌 HTML、進階語法，以及 Mermaid 與數學區塊。
它回答的是讓人每次都得去搜尋的問題：如何對齊表格欄位、如何在編號項目下巢狀清單、如何寫待辦清單、註腳或可收合區塊，以及哪些字元需要跳脫，每一列都附有可行的範例。
與本群組的每份速查表一樣，它免費且在用戶端執行：用搜尋框即時篩選列、用固定的目錄在各段落間跳轉、一鍵複製任何程式碼片段，並可列印頁面在寫作時參考。
如何使用 Markdown 速查表
- 開啟速查表並檢視各段落，從「基本語法」、「清單」到「Mermaid 與數學區塊」。
- 搜尋 table、task list 或 footnote 等關鍵字，即時篩選每一列。
- 跳到「GitHub 風格擴充」，查看只能在 GitHub 及類似平台上運作的語法。
- 點選程式碼片段或其複製圖示，即可將 Markdown 複製到剪貼簿。
- 使用列印取得完整 Markdown 參考的紙本。
常見問題
共十個段落：基本語法、清單、連結與圖片、程式碼與程式碼區塊、表格、引用與分隔線、GitHub 風格擴充、跳脫與 HTML、進階語法，以及 Mermaid 與數學區塊。
包含。待辦清單、表格、刪除線、自動連結、註腳、可收合的 details 區塊、提示框與 emoji 短碼，都各有獨立段落。
「表格」段落展示了以直線與破折號組成的語法，以及冒號位置如何讓每一欄靠左、靠右或置中對齊：複製範例後再修改即可。
可以。點選任一列的 Markdown 或其複製圖示，就會立即複製到剪貼簿。
