I'm using Apache POI to export data to a .xlsx file and I want to style some of the rows and cells contained in the file.
I'm using XSSF since the file is going to be read in Excel 2007+.
Basically, my problem is that I'm trying to set a row style like in the following example, which sets a black foreground color for the entire row at index 0. It works fine, but whenever I create a new cell, the newly created cell has no style, as if it's overriding the row style I specified.
Here's a code snippet to demonstrate what I'm doing:
XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet sheet = wb.createSheet("mySheet");
XSSFRow row = sheet.createRow(0);
XSSFCellStyle myStyle = wb.createCellStyle();
myStyle.setFillForegroundColor(new XSSFColor(new Color(255, 255, 255)));
myStyle.setFillPattern(CellStyle.SOLID_FOREGROUND);
row.setRowStyle(myStyle); //This works, the whole row is now black
row.createCell(0); // This cell doesn't have a style, the rest of the line stays stylized
row.getCell(0).setCellValue("Test");
I also tried *row.createCell(0, Cell.CELL_TYPE_STRING);*, but it didn't change anything.
What is the correct way of accomplishing what I want to do? I wanted to do it this way so I didn't have to set each cell's style after creating it since all cells on the same row have the same style.
