SpreadJS允许您对单元格头部执行各种操作。
此示例变更列头高度和行头宽度。
$(document).ready(function () {
//初始化spread
var spread =new GC.Spread.Sheets.Workbook(document.getElementById("ss"),{sheetCount:3});
//获取活动表
var sheet = spread.getActiveSheet();
// 变更列头高度。
sheet.setRowHeight(0, 90.0,GC.Spread.Sheets.SheetArea.colHeader);
// 变更行头宽度。
sheet.setColumnWidth(0, 90.0,GC.Spread.Sheets.SheetArea.rowHeader);
});
本例将自定义文本放在头部中。
$(document).ready(function () {
//初始化spread
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"),{sheetCount:3});
//获取活动表
var sheet = spread.getActiveSheet();
// 在头部表中设置所需的字符串。
sheet.setValue(1, 0, "Row Header", GC.Spread.Sheets.SheetArea.rowHeader);
sheet.setColumnWidth(1, 120.0,GC.Spread.Sheets.SheetArea.colHeader);
sheet.setColumnWidth(0, 90.0,GC.Spread.Sheets.SheetArea.rowHeader);
});
这个例子设置了头部的背景色和前景色。
$(document).ready(function () {
//初始化spread
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"),{sheetCount:3});
//获取活动表
var sheet = spread.getActiveSheet();
// 设置整个列头的背景色和前景色。
var row = sheet.getRange(0, -1, 1, -1, GC.Spread.Sheets.SheetArea.colHeader);
row.backColor("Red");
row.foreColor("White");
// 设置第二行行头的背景色。
sheet.getCell(1, 0, GC.Spread.Sheets.SheetArea.rowHeader).backColor("Yellow");
});
这个例子隐藏了头部。
$(document).ready(function () {
//初始化spread
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"),{sheetCount:3});
//获取活动表
var activesheet = spread.getActiveSheet();
// 隐藏列头
activeSheet.options.colHeaderVisible = false;
// 隐藏行头
activeSheet.options.rowHeaderVisible = false;
});
下面的代码合并头部中的单元格。
$(document).ready(function () {
//初始化spread
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"),{sheetCount:3});
//获取活动表
var activeSheet = spread.getActiveSheet();
// 将列头的行数设置为3。
activeSheet.setRowCount(3, GC.Spread.Sheets.SheetArea.colHeader);
// 列标头单元格(0,0)扩展为三列。
activeSheet.addSpan(0, 0, 1, 3, GC.Spread.Sheets.SheetArea.colHeader);
// 合并起点在列头单元格(1,0)的两行。
activeSheet.addSpan(1, 0, 2, 1, GC.Spread.Sheets.SheetArea.colHeader);
// 设置合并单元格的字符串。
activeSheet.setValue(0, 0, "Combined Columns", GC.Spread.Sheets.SheetArea.colHeader);
activeSheet.setValue(1, 0, "Combined Rows", GC.Spread.Sheets.SheetArea.colHeader);
// 将行头的列数设置为2。
activeSheet.setColumnCount(2, GC.Spread.Sheets.SheetArea.rowHeader);
// 用行头单元格(1,0)处的原点合并两列和两行。
activeSheet.addSpan(1, 0, 2, 2, GC.Spread.Sheets.SheetArea.rowHeader);
// 为合并的单元格设置字符串。
activeSheet.setValue(1, 0, "Combined rows and columns", GC.Spread.Sheets.SheetArea.rowHeader);
});
此示例在标题中创建多行和多列。
// Initializing Spread
var spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"),{sheetCount:3});
// Get the activeSheet
var activeSheet = spread.getActiveSheet();
// Set number of rows for column headers to 3.
activeSheet.setRowCount(3, GC.Spread.Sheets.SheetArea.colHeader);
//Set number of columns for row header to 4.
activeSheet.setColumnCount(4, GC.Spread.Sheets.SheetArea.rowHeader);});
此示例指定标题文本的类型和位置并创建自定义标题文本。
activeSheet.setRowCount(2,GC.Spread.Sheets.SheetArea.colHeader);
activeSheet.setColumnCount(2,GC.Spread.Sheets.SheetArea.rowHeader);
activeSheet.setValue(0, 2,"Column",GC.Spread.Sheets.SheetArea.colHeader);
activeSheet.options.rowHeaderAutoTextIndex = 1;
activeSheet.options.rowHeaderAutoText = GC.Spread.Sheets.HeaderAutoText.numbers;
activeSheet.options.colHeaderAutoTextIndex = 1;
activeSheet.options.colHeaderAutoText = GC.Spread.Sheets.HeaderAutoText.letters;
您可以使用addRows和addColumns方法在标题中的特定位置添加行或列。它们接受参数,例如行或列索引以及要添加的行数和列数。
同样,您可以使用deleteRows和deleteColumns方法从特定位置删除标题行和列。
以下代码示例显示如何在特定位置的列标题中添加行。
// add rows to column headers
activeSheet.addRows(0, 1, GC.Spread.Sheets.SheetArea.colHeader);
// add column to row headers
activeSheet.addColumns(1, 3, GC.Spread.Sheets.SheetArea.rowHeader);
注意: colHeaderAutoTextIndex 和 rowHeaderAutoTextIndex 选项不会由 addRows/addColumns/deleteRows/deleteColumns 方法自动调整。
当用鼠标选择头部单元格时,此示例获取该头部单元格的索引.
$(document).ready(function () {
var spread = new GC.Spread.Sheets.Workbook($("#ss")[0]);
var activeSheet = spread.getActiveSheet();
activeSheet.setRowCount(4, GC.Spread.Sheets.SheetArea.colHeader);
$("#ss").click(function (e)
// 从列头单元格的鼠标点击处获取单元格索引。
var offset = $("#ss").offset();
var x = e.pageX - offset.left;
var y = e.pageY - offset.top;
var target = spread.getActiveSheet().hitTest(x, y);
if(target &&target.rowViewportIndex === -1 &&
(target.colViewportIndex === 0 || target.colViewportIndex === 1))
{
console.log("Row index of mouse-clicked column header cells: " + target.row);
console.log("Column index of mouse-clicked column header cells: " + target.col);
}
});
您可以将公式(平均值、最小值、最大值等)和SparklineEx (LineSparkline、ColumnSparkline、WinlossSparkline、CascadeSparkline、PieSparkline等)添加到表格的行头部区域和列头部区域。用户可以方便地绑定数据源,在头部区域进行数据可视化和数据聚合。此外,它有助于显示总体进度和分析数据中的错误,而不必遍历所有数据值。在头部中添加公式就像冻结行和列一样,无论用户在哪里滚动,它们都将始终显示。
举个例子,在过去的8年里,在2012年到2019年间,一个组织里的三名员工Andrey, Michael和John的绩效被评估。在下面描述的用例图像中,“实际销售”表示在特定年份由3名员工完成的销售总额,“销售目标”表示公司在特定年份的目标销售。此外,“销售赤字”表示实际销售和销售目标之间的差异。
在这里,我们代表一个用于销售业绩分析的仪表板,其中我们在列头中使用 LineSparkline 公式来表示员工在过去8年的销售,在列头部中使用 ColumnSparkline 公式来表示实际销售和销售目标。此外,销售亏损列头部中的 WinLossSparkline 公式表示实际销售和销售目标之间的差异。
同样,为了在列头部中显示数据聚合,我们使用了内置函数公式,并描述了员工的最低、平均和最大销售额、实际销售额、销售目标和销售赤字。
在仪表板表单中使用SparklineEx和数据聚合公式时,用户可以很容易地识别不同参数上的性能,而不必遍历实际值。
使用代码
下面的代码片段显示了SparklineEx和公式在头部中的使用:

Excel不支持自定义头部区域。但如果用户想要导入和导出的公式头在Excel中,他们可以使用frozenColumnsAsRowHeaders或frozenRowsAsColumnHeaders rowHeadersAsFrozenColumns或columnHeadersAsFrozenRows SpreadJS的属性。如果您启用了这些属性,头部区域中的公式将被保留。此外,这些将在导出期间转换为冻结区域,并在导入期间转换为头部区域。
注意 : 视窗引用可以由头文件引用,但是头文件的引用只能由它自己引用。但是,这不会处理范围,它跨越冻结的情况。另外,SparklineEx在头部区域不支持ExcelIO。
