/**

> Creates and item-based table view.

* **This class is a JS wrapper around Qt's [QTableWidget class](https://doc.qt.io/qt-5/qtablewidget.html)**

### Example

```javascript
const { QTableWidget, QMainWindow, QTableWidgetItem } = require("@nodegui/nodegui");

const win = new QMainWindow();
const table = new QTableWidget(2, 3);
table.setHorizontalHeaderLabels(['first', 'second', 'third']);

const cell00 = new QTableWidgetItem('C00');
const cell01 = new QTableWidgetItem('C01');
const cell10 = new QTableWidgetItem('C10');
const cell11 = new QTableWidgetItem('C11');

table.setItem(0, 0, cell00);
table.setItem(0, 1, cell01);
table.setItem(1, 0, cell10);
table.setItem(1, 1, cell11);

win.setCentralWidget(table);
win.show();
(global as any).win = win;

```
