SpreadJSは、1つのシートは4つの領域で構成されます。
corner
colHeader
rowHeader
viewport
つまり、シートには行ヘッダと列ヘッダの2つのヘッダがあり、どちらのヘッダも複数行および複数列で作成できます。
ヘッダ行およびヘッダ列のいずれか1つでは、列および行のインデックスを示す自動テキストが各セルに表示されます。自動テキストが表示される行または列を確認したい場合や、指定の行または列に自動テキストを表示させたい場合には、次のようなコードを使用します。
SpreadJSでは、ヘッダの自動テキストとして空白、文字、数字の3タイプを選択できます。
行ヘッダまたは列ヘッダを非表示にすることもできます。次のコードは、行ヘッダ内のすべての行を非表示にします。

var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
