Вы можете использовать следующий код php:
// Set grid with 1000px by php
$grid->setGridOptions(array("width"=>1000));
У меня была такая же проблема, моя сетка по умолчанию принимала 650px с.Итак, я проверяю некоторый блог, а также wiki , и теперь он заканчивается:)
Вот мой полный php-код с автоматической шириной сетки:
<?php
require_once '../../../jq-config.php';
// include the jqGrid Class
require_once ABSPATH."php/jqGrid.php";
// include the driver class
require_once ABSPATH."php/jqGridPdo.php";
// Connection to the server
$conn = new PDO(DB_DSN,DB_USER,DB_PASSWORD);
// Tell the db that we use utf-8
$conn->query("SET NAMES utf8");
// Create the jqGrid instance
$grid = new jqGridRender($conn);
// SQL query
$sql = <<<SQL
SELECT *,
CASE total_correct_answer
WHEN total_correct_answer=1 THEN 1
WHEN total_correct_answer=2 THEN 3
