$xlsFirstTable = $workbook->easy_getSheetAt(0)->easy_getExcelTable();

// Create the formatting style for the header
$xlsStyleHeader = new COM("EasyXLS.ExcelStyle");

$xlsStyleHeader->setFontSize(8);
$xlsStyleHeader->setItalic(True);

    $xlsFirstTable->easy_getCell(0,$column)->setStyle($xlsStyleHeader);
}
$xlsFirstTable->easy_getRowAt(0)->setHeight(30);

// Create a formatting style for cells
$xlsStyleData = new COM("EasyXLS.ExcelStyle");

                                                               ", " . ($column + 1));
        $xlsFirstTable->easy_getCell($row+1,$column)->setStyle($xlsStyleData);
    }
}

// Set column widths
$xlsFirstTable->setColumnWidth_2(0, 70);
$xlsFirstTable->setColumnWidth_2(1, 100);
$xlsFirstTable->setColumnWidth_2(2, 70);
$xlsFirstTable->setColumnWidth_2(3, 100);
$xlsFirstTable->setColumnWidth_2(4, 70);

// Create Excel file
echo "Writing file: C:\Samples\Tutorial06 - protect Excel sheet.xlsx<br>";
$workbook->easy_WriteXLSXFile("C:\Samples\Tutorial06 - protect Excel sheet.xlsx");

// Confirm the creation of Excel file
if ($workbook->easy_getError() == "")
    echo "File successfully created.";
else
    echo "Error encountered: " . $workbook->easy_getError();

// Dispose memory
$workbook->Dispose();
$workbook = null;
$xlsStyleHeader = null;
$xlsStyleData = null;

?>

Overloaded methods
For methods with same name but different parameters, only the first method overload retains the original name. Subsequent overloads are uniquely renamed by appending to the method name '_2', '_3', etc (method, method_2, method_3), an integer that corresponds to the order of declaration that can be found in EasyXLS.h, a file that comes with EasyXLS installation.
