數(shù)據(jù)表也稱為模擬運算表，是Excel圖表的一種元素，它可以在圖表的下方顯示數(shù)據(jù)源中的數(shù)據(jù)。本文將介紹如何使用Spire.XLS給Excel圖表添加數(shù)據(jù)表。

【下載Spire.XLS最新試用版】

//創(chuàng)建Workbook實例
Workbook workbook = new Workbook();

//獲取第一張工作表
Worksheet sheet = workbook.Worksheets[0];

//向工作表中添加數(shù)據(jù)
sheet.Range["A1"].Text = "月份";
sheet.Range["A2"].Text = "7月銷量";
sheet.Range["A3"].Text = "8月銷量";
sheet.Range["A4"].Text = "9月銷量";           

sheet.Range["B1"].Text = "海爾";
sheet.Range["B2"].NumberValue = 950;
sheet.Range["B3"].NumberValue = 500;
sheet.Range["B4"].NumberValue = 900;            
            
sheet.Range["C1"].Text = "美的";
sheet.Range["C2"].NumberValue = 680;
sheet.Range["C3"].NumberValue = 720;
sheet.Range["C4"].NumberValue = 890;
            
sheet.Range["D1"].Text = "格力";
sheet.Range["D2"].NumberValue = 980;
sheet.Range["D3"].NumberValue = 1070;
sheet.Range["D4"].NumberValue = 1200;

//插入圖表
Chart chart = sheet.Charts.Add(ExcelChartType.Column3DClustered);
chart.DataRange = sheet.Range["B1:D4"];
chart.SeriesDataFromRange = false;
chart.TopRow = 7;
chart.BottomRow = 28;
chart.LeftColumn = 3;
chart.RightColumn = 11;
chart.ChartTitle = "第三季度產(chǎn)品銷量分析";
chart.ChartTitleArea.IsBold = true;
chart.ChartTitleArea.Size = 12;
Spire.Xls.Charts.ChartSerie cs1 = chart.Series[0];
cs1.CategoryLabels = sheet.Range["A2:A4"];

//顯示數(shù)據(jù)表
chart.HasDataTable = true;

//保存文件
workbook.SaveToFile("AddDataTable.xlsx", ExcelVersion.Version2010);
