## zh-CN

可以简单配置几种等分栅格和间距。

## en-US

A simple playground for column count and gutter.

```jsx
import { Row, Col, Slider } from 'antd';

class App extends React.Component {
  gutters = {};

  vgutters = {};

  colCounts = {};

  constructor() {
    super();

      gutterKey: 1,
      vgutterKey: 1,
      colCountKey: 2,
    };
    [8, 16, 24, 32, 40, 48].forEach((value, i) => {
      this.gutters[i] = value;
    });
    [8, 16, 24, 32, 40, 48].forEach((value, i) => {
      this.vgutters[i] = value;
    });
    [2, 3, 4, 6, 8, 12].forEach((value, i) => {
      this.colCounts[i] = value;
    });
  }

  onGutterChange = gutterKey => {
    this.setState({ gutterKey });
  };

  onVGutterChange = vgutterKey => {
    this.setState({ vgutterKey });

    let colCode = '';
