Excel Cell Border alignment
  • EPPlus supports Top, Left, Right, Bottom, Diagonal, DiagonalDown,DiagonalUp alignments. These alignment properties are assigned by different types of ExcelBorderStyle class properties.

  • For Example: Thin, Medium, Thick, DashDot, DashDotDot, Dashed, Dotted,Double, Hair, MediumDashDot, MediumDashDotDot, MediumDashed, none.
Example
  • ExcelRange Rng = new ExcelRange();
  • Rng.Style.Border.Top.Style = ExcelBorderStyle.Thin; Rng.Style.Border.Left.Style = ExcelBorderStyle.Medium; Rng.Style.Border.Right.Style = ExcelBorderStyle.Thin; Rng.Style.Border.Bottom.Style = ExcelBorderStyle.Thick;
*By default, EPPlus supports no border, if you are not specifying any border style. Now, the next question in our mind is how to apply cell border color?

Example
  • Rng.Style.Border.Top.Color.SetColor(Color.Red);
  • Here SetColor method can support structure Color property as a parameter.
  • You can also specify the HTML Color code.
For Example
  • Color DeepBlueHexCode = ColorTranslator.FromHtml("#254061");
  • Rng.Style.Border.Top.Color.SetColor(DeepBlueHexCode);
  • In this example FromHtml() directly accept HTML RGB (Red Green Blue) color Code.
Output on an Excel sheet is given below.



Source code
  1. using OfficeOpenXml;
  2. using System.IO;
  3. using System;
  4. //add two new namespace
  5. using OfficeOpenXml.Style;
  6. using System.Drawing;
  7. class Program {
  8. static void Main(string[] args) {
  9. ExcelPackage ExcelPkg = new ExcelPackage();
  10. ExcelWorksheet wsSheet1 = ExcelPkg.Workbook.Worksheets.Add("Sheet1");
  11. using(ExcelRange Rng = wsSheet1.Cells[2, 2, 2, 2]) {
  12. Rng.Value = "Welcome to Everyday be coding - tutorials for beginners";
  13. Rng.Style.Font.Size = 16;
  14. Rng.Style.Font.Bold = true;
  15. Rng.Style.Font.Italic = true;
  16. }
  17. Color DeepBlueHexCode = ColorTranslator.FromHtml("#254061");
  18. //First Border Box
  19. using(ExcelRange Rng = wsSheet1.Cells[5, 2, 8, 4]) {
  20. Rng.Value = "Thin";
  21. Rng.Merge = true;
  22. Rng.Style.Border.Top.Style = ExcelBorderStyle.Thin;
  23. Rng.Style.Border.Top.Color.SetColor(Color.Red);
  24. Rng.Style.Border.Left.Style = ExcelBorderStyle.Thin;
  25. Rng.Style.Border.Left.Color.SetColor(Color.Green);
  26. Rng.Style.Border.Right.Style = ExcelBorderStyle.Thin;
  27. Rng.Style.Border.Right.Color.SetColor(Color.Green);
  28. Rng.Style.Border.Bottom.Style = ExcelBorderStyle.Thin;
  29. Rng.Style.Border.Bottom.Color.SetColor(DeepBlueHexCode);
  30. }
  31. wsSheet1.Protection.IsProtected = false;
  32. wsSheet1.Protection.AllowSelectLockedCells = false;
  33. ExcelPkg.SaveAs(new FileInfo(@ "D:\New.xlsx"));
  34. }
  35. }
Now, build & execute the code. File is (New.xlsx), which is stored on D: drive of the computer.
