Cell Formatting

cursor
  .move('A1')
  .setData('Styled Cell')
  .formatCell({
    font: { 
      bold: true,
      color: '#FF0000',
      size: 14
    },
    fill: {
      type: 'pattern',
      pattern: 'solid',
      fgColor: '#FFFF00'
    },
    border: {
      top: { style: 'thin', color: '#000000' },
      bottom: { style: 'thin', color: '#000000' }
    }
  });

Cell Merging

cursor
  .move('A1')
  .setData('Merged Cells')
  .colSpan(3)  // Merge 3 columns
  .formatCell({
    alignment: { horizontal: 'center' }
  });

Working with Multiple Sheets

const cursor = new ExcelCursor(workbook, 'Sheet1');
// Work with Sheet1
cursor.move('A1').setData('Sheet 1 Data');

// Create and switch to a new sheet
const sheet2 = workbook.addWorksheet('Sheet2');
cursor.switchSheet('Sheet2');
cursor.move('A1').setData('Sheet 2 Data');
