Set Print Titles in xlsx4j
Aspose.Cells - Set Print Titles
Aspose.Cells allows you to designate row and column headers to repeat on all pages of a printed worksheet. To do so, use the PageSetup class’setPrintTitleColumns and setPrintTitleRows properties.
The rows or columns that will be repeated are defined by passing their row or column numbers. For example, rows are defined as $1:$2 and columns are defined as $A:$B.
//Obtaining the reference of the PageSetup of the worksheet PageSetup pageSetup = sheet.getPageSetup(); //Defining column numbers A & B as title columns pageSetup.setPrintTitleColumns("$A:$B"); //Defining row numbers 1 & 2 as title rows pageSetup.setPrintTitleRows("$1:$2");
