Epplus使用技巧

废话不说，直接开始。

创建Excel工作表

private static ExcelWorksheet CreateSheet(ExcelPackage p, string sheetName)

 {

    p.Workbook.Worksheets.Add(sheetName);

    ExcelWorksheet ws = p.Workbook.Worksheets[1];

    ws.Name = sheetName; //Setting Sheet's name

    ws.Cells.Style.Font.Size = 11; //Default font size for whole sheet

    ws.Cells.Style.Font.Name = "Calibri"; //Default Font name for whole sheet

    return ws;

 }

 

合并的Excel列

//Merging cells and create a center heading for out table

ws.Cells[1, 1].Value = "Sample DataTable Export"; // Heading Name

ws.Cells[1, 1, 1, dt.Columns.Count].Merge = true; //Merge columns start and end range

ws.Cells[1, 1, 1, dt.Columns.Count].Style.Font.Bold = true; //Font should be bold

ws.Cells[1, 1, 1, dt.Columns.Count].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center; // Aligmnet is center

 

Excel单元格背景颜色

//Setting the background color of header cells to Gray

var fill = cell.Style.Fill;

fill.PatternType = ExcelFillStyle.Solid;

fill.BackgroundColor.SetColor( Color.Gray);

 

Excel单元格边框

//Setting Top/left,right/bottom borders.

var border = cell.Style.Border;

border.Bottom.Style = border.Top.Style = border.Left.Style = border.Right.Style = ExcelBorderStyle.Thin;

 

Excel公式

//Setting Sum Formula

cell.Formula = "Sum(" + ws.Cells[3, colIndex].Address + ":" + ws.Cells[rowIndex - 1, colIndex].Address + ")";

 

添加注释到Excel单元格

private static void AddComment(ExcelWorksheet ws, int colIndex, int rowIndex, string comment, string author)

{

    //Adding a comment to a Cell

    var commentCell = ws.Cells[rowIndex, colIndex];

    commentCell.AddComment(comment, author);

}

 

添加图像在Excel工作表

private static void AddImage(ExcelWorksheet ws, int columnIndex, int rowIndex, string filePath)

{

    //How to Add a Image using EP Plus

    Bitmap image = new Bitmap(filePath);

    ExcelPicture picture = null;

    if (image != null)

    {

        picture = ws.Drawings.AddPicture( "pic" + rowIndex.ToString() + columnIndex.ToString(), image);

        picture.From.Column = columnIndex;

        picture.From.Row = rowIndex;

        picture.From.ColumnOff = Pixel2MTU(2); //Two pixel space for better alignment

        picture.From.RowOff = Pixel2MTU(2); //Two pixel space for better alignment

        picture.SetSize(100, 100);

    }

}

 

添加自定义对象到Excel工作表

private static void AddCustomShape(ExcelWorksheet ws, int colIndex, int rowIndex, eShapeStyle shapeStyle, string text)

{

    ExcelShape shape = ws.Drawings.AddShape("cs" + rowIndex.ToString() + colIndex.ToString(), shapeStyle);

    shape.From.Column = colIndex;

    shape.From.Row = rowIndex;

    shape.From.ColumnOff = Pixel2MTU(5);

    shape.SetSize(100, 100);

    shape.RichText.Add(text);

}
