Sheet.tag(value?): 设置或者获取表单上的标签。
Sheet.getTag(row, col, sheetArea?) / Sheet.setTag(row, col, tag, sheetArea?): 也可以通过以下方式为不同的单元设置标签：
表单: 当 row 和 col 都为 -1 时
行: 当 col 为 -1 并且 row 大于等于 0 时
列: 当 row 为 -1 并且 col 大于等于 0 时
单元格: 当 row 大于等于 0 并且 col 大于等于 0 时
CellRange.tag(value?): 设置或者获取单元格上的标签。
当设置标签的时，会触发以下事件，你可以监听此类事件完成自己的业务逻辑：
CellChanged 事件在设置单元格标签时触发，比如 CellRange.tag(value)
RowChanged 事件在设置行标签时触发，比如 CellRange.tag(value)
ColumnChanged 事件在设置列标签时触发，比如 CellRange.tag(value)
你可以设置标签为 null 或者 undefined 或者使用 Sheet.clear(row, column, rowCount, columnCount, sheetArea, StorageType.Tag) 方法来删除标签。例如：
window.onload = function () {
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), {sheetCount: 1});
spread.suspendPaint();
initSpread(spread);
bindEvents(spread.getActiveSheet());
spread.resumePaint();
};
function bindEvents(sheet) {
sheet.bind(GC.Spread.Sheets.Events.SelectionChanged, function () {
getTag(sheet);
});
}
function getTag(sheet) {
var selections = sheet.getSelections();
if (!selections || selections.length === 0) {
return;
}
var sel = selections[0],
row = sel.row,
col = sel.col,
tag = document.getElementById('txtTag');
if (row === -1 && col === -1) {
tag.value = sheet.tag() !== undefined ? sheet.tag() : "";
} else {
tag.value = sheet.getTag(row, col)!== undefined ? sheet.getTag(row, col) : "";
}
};
function initSpread(spread) {
var spreadNS = GC.Spread.Sheets, sheet = spread.sheets[0];
// sheet tag
sheet.tag("Sheet tag");
// row tag
sheet.setTag(3, -1, "Row 4 tag");
sheet.getRange(5, -1, 1, -1).tag("Row 6 tag");
sheet.getCell(5, -1, GC.Spread.Sheets.SheetArea.rowHeader).backColor('#82bc00');
// column tag
sheet.getRange(-1, 4, -1, 3).tag("Column E-G tag");
sheet.getCell(-1, 4, GC.Spread.Sheets.SheetArea.colHeader).backColor('#82BC00');

sheet.getCell(0, 0).tag("A1 tag");
sheet.getCell(0, 0).backColor("#E3E3E3");
sheet.getRange(6, 0, 4, 3).tag("Cells tag (A7:C10)");
sheet.getRange(6, 0, 4, 3).backColor("#E3E3E3");
