There are primary button, default button, dashed button and link button in antd.

Ant Design supports a default button size as well as a large and small size.

If a large or small button is desired, set the size property to either large or small respectively. Omit the size property for a button with the default size.

A loading indicator can be added to a button by setting the Loading parameter on the Button.

Use the AutoLoading parameter to automatically add and deactivate load states for asynchronous methods that bind the OnClick callback.

ghost property will make button's background transparent, it is commonly used in colored background.

block property will make the button fit to its parent width.

Button components can contain an Icon. This is done by setting the icon property or placing an Icon component within the Button.

If you want specific control over the positioning and placement of the Icon, then that should be done by placing the Icon component within the Button rather than using the icon property.

To mark a button as disabled, add the disabled property to the Button.

If you need several buttons, we recommend that you use 1 primary button + n secondary buttons, and if there are more than three operations, you can group some of them into DropdownButton.

danger is a property of button after antd 4.0.

DownloadButton provides a simple implementation of file download, which may meet the needs of most situations.

When Url is null or empty, this button won't trigger file download.

FileName is actually the download attribute of <a/>. About its description and limit, please read MDN Doc.
