PdfGridColumnCollection columns = grid.columns;
//Add columns to grid
columns.add(column: column);
columns.add(count: 2);
//Gets column count
int columnCount = columns.count;
//Add headers to grid
grid.headers.add(1);
PdfGridRow header = grid.headers[0];
header.cells[0].value = 'Employee ID';
header.cells[1].value = 'Employee Name';
header.cells[2].value = 'Salary';
//Add rows to grid
PdfGridRow row1 = grid.rows.add();
row1.cells[0].value = 'E01';
row1.cells[1].value = 'Clay';
row1.cells[2].value = '\$10,000';
PdfGridRow row2 = grid.rows.add();
row2.cells[0].value = 'E02';
row2.cells[1].value = 'Simon';
row2.cells[2].value = '\$12,000';
//Set the width
grid.columns[1].width = 50;

grid.columns[0].format = PdfStringFormat(
    alignment: PdfTextAlignment.center,
    lineAlignment: PdfVerticalAlignment.bottom);
//Draw the grid in PDF document page
grid.draw(
    page: document.pages.add(), bounds: Rect.zero);
//Save the document.
List<int> bytes = await document.save();
//Dispose the document.
