Format many columns at once

I currently have a sheet that I need to format many columns. The columns are not always next to each other. Is it possible to accomplish without adding the style one column at a time? I was thinking of something like CreateRange("L:L,P:P,R:R,AA:AA") to create this range then I would apply the style for these four columns. Also I noticed a RangeCollection class, do I need to use that? I looked at the examples but I could not find a way to utilize the RangeCollection class to get this done.



I think you may try to use NameCollection and create Name object to specify your desired ranges for your requirements. I have written a sample code for your reference, please refer to it and accomplish your tasks accordingly:

Sample code:
Workbook workbook = new Workbook();
Worksheet sheet = workbook.Worksheets[0];

Cells cells = sheet.Cells;

NameCollection names = workbook.Worksheets.Names;
Name name = names[names.Add(“Myrange1”)];
name.RefersTo = “=Sheet1!$A:$A, Sheet1!$C:$C”;
Style style = workbook.Styles[workbook.Styles.Add()];
style.ForegroundColor = Color.Yellow;
style.Pattern = BackgroundType.Solid;
StyleFlag flag = new StyleFlag();
flag.CellShading = true;

Range[] rngs = name.GetRanges();
if (rngs != null)

for (int i = 0; i < rngs.Length; i++)
rngs[i].ApplyStyle(style, flag);
