SpreadJSで enableAccessibility を true にすると、アクセシビリティが有効になります。
SpreadJSは次の方法でフォーカスを取得することができます。
1．コマンドマネージャーでキーが moveToNextCellThenControl 、 selectNextControl 、 moveToPreviousCellThenControl または selectPreviousControl に登録されているときに、[Tab]キー、または[Shift] + [Tab]キーを押下します。
ワークブックでマウスボタンを押下します。
ワークブックの focus()メソッドを実行します。
以下は一般的なスクリーンリーダーです。

window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(_getElementById('ss'), { sheetCount: 1 });
initSpread(spread);
};
function initSpread(spread) {
spread.suspendPaint();
//enable accessibility
spread.options.enableAccessibility = true;
//set focus
spread.focus();
//change the commands related to Tab key, Shift key with Tab key
var commands = spread.commandManager();
//TAB
commands.register("moveToNextCellThenControl", GC.Spread.Sheets.Commands.moveToNextCellThenControl, GC.Spread.Commands.Key.tab, false, false, false, false);
//SHIFT+TAB
commands.register("moveToPreviousCellThenControl", GC.Spread.Sheets.Commands.moveToPreviousCellThenControl, GC.Spread.Commands.Key.tab, false, true, false, false);
var sheet = spread.getActiveSheet();
//set default row height and column width
sheet.defaults.rowHeight = 50;
sheet.defaults.colWidth = 150;
//set default horizontal alignment and vertical alignment
var defaultStyle = sheet.getDefaultStyle();
defaultStyle.hAlign = GC.Spread.Sheets.HorizontalAlign.center;
defaultStyle.vAlign = GC.Spread.Sheets.VerticalAlign.center;
sheet.setDefaultStyle(defaultStyle);
//bind data source
sheet.setDataSource(dataSource);
spread.resumePaint();
