Basic sales table
EnableTablesTurns a written range into a real Excel table — banded rows, filter buttons, and a structured name that formulas elsewhere can reference.
Write.cs
using FormulaEngineer.Api;
using FormulaEngineer.Api.Styling;
var stylingOptions =
new ExcelStylingOptions
{
EnableTables = true
};
using (var writer = new ExcelStyledWriter("basic-sales-table.xlsx", null, stylingOptions))
{
using (var sheet = writer.CreateWorksheet("Sales"))
{
sheet.WriteRow("Product", "Quantity", "Revenue");
sheet.WriteRow("Formula Engine", 5, 2495m);
sheet.WriteRow("Streaming Writer", 3, 825m);
sheet.WriteRow("Dashboard Pack", 2, 1500m);
sheet.AddTable(
ExcelTable.Create(
"SalesTable",
"A1:C4",
new[]
{
ExcelTableColumn.Create("Product"),
ExcelTableColumn.Create("Quantity"),
ExcelTableColumn.Create("Revenue")
},
ExcelTableStyle.Create("TableStyleMedium2")));
}
writer.Close();
}
Style your own workbooks
Styling is part of the same package — no separate install, no Excel, no COM automation.
