Formula attribute added to support in rows with dto or dynamic attrib…

[RaZer0k]

I added the support of formula rows values... i tested with =hyperlink("") without problems.
You can add the parameter "Type = ColumnType.Formula" into the DTO or create a dynamic columns setting with the "Type
= ColumnType.Formula" parameter.

var dColumns = new[]
{
    new DynamicExcelColumn("Url")
    {
        Width = 100,
        Type = ColumnType.Formula
    }
};

var config = new OpenXmlConfiguration
{
    TableStyles = TableStyles.None,
    AutoFilter = false,
    DynamicColumns = dColumns
};

MiniExcel.SaveAs(stream, _sheets, configuration: config);

Or

[ExcelColumn(Name = "Url Document", Type = ColumnType.Formula, Width = 16)] public string Url { get; set; }

Adding this column to use formula:

row.Add("Url", $"=HYPERLINK(\"{doc.Url ?? ""}\")");

Update: Added enum type for the new Type parameter

Hi, is there any ETA on when this will be released to NuGet?

@RaZer0k - Your fix works well but conflicts with EnableAutoWidth configuration setting.

Using version 1.36.0

I applied the attribute [ExcelColumn(Name = "CRM URL", Type = ColumnType.Formula)] to a class property. The formula part worked great but the EnableAutoWidth = true configuration value set the column width based on the text of the formula ("=HYPERLINK(URL, Label)") plus about 30%, instead of the label of the HYPERLINK.

Thank you for your great effort on this project!!
