Markdown テーブルジェネレーターの使い方





機能概要


Markdown テーブルを手書きすると、縦線や区切り行の数え間違いが起きやすいものです。このツールでは表形式の画面で編集し、構文をリアルタイムで生成できます。




使い方



  • Excel や Web ページの表からデータをコピーし、「インポート」欄に貼り付けて「表としてインポート」をクリックすると、Tab、縦線、カンマで自動的に列に分割されます

    • 

  • 下の表に直接セルごとに入力し、「+ 行 / - 行 / + 列 / - 列」で規模を調整することもできます

    • 

  • 揃え方（左揃え / 中央揃え / 右揃え）と、先頭列を太字にするかを選択します

    • 

  • 「空白で埋めてソースを揃える」をオンにすると生成結果が読みやすくなり、オフにすると短くなります

    • 

  • 右上の「コピー」をクリックして Markdown テーブルをコピーします

    • 

    

    注意事項

    

  • セルに元からある縦線 `|` は自動的に `\|` にエスケープされ、表が崩れることはありません

    • 

  • セル内の改行はスペースに置き換えられます（Markdown テーブル構文はセル内改行に対応していません）

    • 

  • インポート時の区切り文字は先頭行から自動判定されます。区切り文字が混在した汚いデータは、先に整理してから貼り付けることをおすすめします
    •     
    

    



    
    
    ❓ FAQ
    
    
    
                
    
            
                Why did the number of columns increase after importing?                
            
            
    This usually happens because one row has more cells than the header. The tool pads the other rows to match the longest row. Just remove the extra commas or tabs before pasting.
    
        
    
                
    
            
                What if the cell content contains a pipe?                
            
            
    The tool automatically escapes pipes to `\|`, so the table will not be split into extra columns. You do not need to handle it manually.
    
        
    
                
    
            
                Can the generated table be used directly on GitHub?                
            
            
    Yes. The output is standard GitHub Flavored Markdown table syntax, and it renders correctly when pasted into a README, an Issue, or any editor that supports Markdown.
