DsExcel Java enables users to create custom table style elements and apply them to a worksheet using the ITableStyle interface. Also, users can format a table using any of the predefined table styles as per their preferences.

Generally, each workbook stores both built-in and custom table styles. If you want to insert a custom table style, you use the add method of the ITables interface, which returns the IStyle object representing the corresponding table style instance.

In order to apply table style in a worksheet, refer to the following example code.

// Use table style name get one build in table style.
ITableStyle tableStyle = workbook.getTableStyles().get("TableStyleLight11");
worksheet.getTables().add(worksheet.getRange(0, 0, 2, 2), true);

// Set built-in table style to table.
worksheet.getTables().get(0).setTableStyle(tableStyle);
