在智能标记字段中使用公式参数

可能的使用场景

有时，您想在智能标记字段中嵌入公式。本文介绍了如何使用公式在智能标记字段中嵌入公式的参数。

在智能标记字段中使用公式参数

以下示例代码将公式嵌入名为TestFormula的智能标记字段中，其数据源名称为MyDataSource，因此带有公式参数的完整字段类似于&=MyDataSource.TestFormula(formula)，代码执行后，最终输出Excel文件将在 A1 到 A5 的单元格中包含公式。

示例代码

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET

//Create a datatable and add column named TestFormula
DataTable dt = new DataTable();
dt.Columns.Add("TestFormula");

//Create first row with formula (which basically concatenates three strings)
DataRow dr = dt.NewRow();
dr["TestFormula"] = "=\"01-This \" & \"is \" & \"concatenation\"";
dt.Rows.Add(dr);

//Create second row like above
dr = dt.NewRow();
dr["TestFormula"] = "=\"02-This \" & \"is \" & \"concatenation\"";
dt.Rows.Add(dr);

//Create third row like above
dr = dt.NewRow();
dr["TestFormula"] = "=\"03-This \" & \"is \" & \"concatenation\"";
dt.Rows.Add(dr);

//Create fourth row like above
dr = dt.NewRow();
dr["TestFormula"] = "=\"04-This \" & \"is \" & \"concatenation\"";
dt.Rows.Add(dr);

//Create fifth row like above
dr = dt.NewRow();
dr["TestFormula"] = "=\"05-This \" & \"is \" & \"concatenation\"";
dt.Rows.Add(dr);

//Set the name of the data table
dt.TableName = "MyDataSource";

//Create a workbook
Workbook wb = new Workbook();

//Access first worksheet
Worksheet ws = wb.Worksheets[0];

//Put the smart marker field with formula parameter in cell A1
ws.Cells["A1"].PutValue("&=MyDataSource.TestFormula(Formula)");

//Create workbook designer, set data source and process it
WorkbookDesigner wd = new WorkbookDesigner(wb);
wd.SetDataSource(dt);
wd.Process();

//Save the workbook in xlsx format
wb.Save(outputDir + "outputUsingFormulaParameterInSmartMarkerField.xlsx");
