c# - EPPlus isn't honoring ExcelHorizontalAlignment Center or Right -

-

i've tried in epplus versions 3.1.3.0 , latest 4.0.4.0 , both exhibiting same behavior.

i'm trying center align text in cells it's not working. numbers in cells work fine, strings not. following example of code fails produce desired excelhorizontalalignment:

var newfile = new fileinfo(@"c:\temp\sample.xlsx"); using (var package = new excelpackage(newfile)) {     var worksheet = package.workbook.worksheets.add("content");      worksheet.column(1).width = 50;      worksheet.cells["a1"].value = "this should left-aligned";     worksheet.cells["a1"].style.horizontalalignment = excelhorizontalalignment.left;       worksheet.cells["a2"].value = "this should center-aligned";     worksheet.cells["a2"].style.horizontalalignment = excelhorizontalalignment.center;      // <-  doesn't work.      worksheet.cells["a3"].richtext.add("this should center-aligned");     worksheet.cells["a3"].style.horizontalalignment = excelhorizontalalignment.center;      // <-  doesn't work.       worksheet.cells["a4"].value = "this should right-aligned";     worksheet.cells["a4"].style.horizontalalignment = excelhorizontalalignment.right;       // <-  doesn't work.      worksheet.cells["a5"].richtext.add("this should right-aligned");     worksheet.cells["a5"].style.horizontalalignment = excelhorizontalalignment.right;       // <-  doesn't work.       //worksheet.cells["a2:a3"].style.horizontalalignment = excelhorizontalalignment.center; // <-  doesn't work.     //worksheet.cells["a4:a5"].style.horizontalalignment = excelhorizontalalignment.center; // <-  doesn't work.      package.save(); }

it's making me little crazy. ideas why strings cannot aligned?

it seems though libreoffice partially @ fault. if generate file epplus, , open in calc, center , right alignment not displayed. if open file in epplus, formatting general.

if, however, generate file using epplus , read in epplus, alignment specified.

i have solution works in calc , excel. if create namedstyle, , apply cells or cell-ranges, works expected.

var newfile = new fileinfo(filepath); using (var package = new excelpackage(newfile)) {     var worksheet = package.workbook.worksheets.add("content");      worksheet.column(1).width = 50;      worksheet.cells["a1"].value = "this should left-aligned";     worksheet.cells["a1"].style.horizontalalignment = excelhorizontalalignment.left;      var centerstyle = package.workbook.styles.createnamedstyle("center");     centerstyle.style.horizontalalignment = excelhorizontalalignment.center;      worksheet.cells["a2"].value = "this should center-aligned";     worksheet.cells["a3"].richtext.add("this should center-aligned");     worksheet.cells["a2:a3"].stylename = "center";      var rightstyle = package.workbook.styles.createnamedstyle("right");     rightstyle.style.horizontalalignment = excelhorizontalalignment.right;      worksheet.cells["a4"].value = "this should right-aligned";     worksheet.cells["a5"].richtext.add("this should right-aligned");     worksheet.cells["a4:a5"].stylename = "right";      package.save(); }
