            //Create style for table number format
            IStyle style1 = workbook.Styles.Add("CurrencyFormat");
            style1.NumberFormat = "_($* #,##0.00_);_($* (#,##0.00);_($* \" - \"??_);_(@_)";

ShowTableStyleColumnStripes

Gets or sets a Boolean value indicating whether column stripes should be present.

Declaration

bool ShowTableStyleColumnStripes { get; set; }

Property Value

Type
System.Boolean

Remarks

Similar to ShowTableStyleRowStripes and ShowTableStyleColumnStripes, ShowHeaderRow and ShowTotals properties are used to alter first and last rows of the table.

Examples

By default ShowTableStyleColumnStripes is set to "False", So formatting is applied only to table rows. Here for example, We set ShowTableStyleColumnStripes to "True" and ShowTableStyleRowStripes to "False" to change the default formatting of the table.

ShowTableStyleRowStripes

Gets or sets a Boolean value indicating whether row stripes should be present.

Declaration

bool ShowTableStyleRowStripes { get; set; }

Property Value

Type
System.Boolean

Examples

ShowTableStyleRowStripes property is set to "True" by default. This allows table to show alternate shades of color present in the table style. Here for example, We set ShowTableStyleRowStripes to "False" and set ShowTableStyleColumnStripes to "True" to enable table formatting in columns only.

        using (ExcelEngine excelEngine = new ExcelEngine())

Here for example, We enable it by setting it to "True" and show the sum of values in second and third columns in the totals row.
