这里列了几种web方案，有些不支持linux，cefnet尝试了下，linux也能用，但需要系统重某些依赖包要升级，导致安装比较麻烦。

Web Browsers

• CefGlue - .NET/Mono binding for The Chromium Embedded Framework (CEF).
• CefNet - .NET binding for the Chromium Embedded Framework (CEF).
• DotNetBrowser - Premium Chromium web browser control for Windows, macOS and Linux.
• OutSystems WebView - Fully featured Avalonia WebView Control.
• Avalonia BlazorWebView & Avalonia WebView - Native host webview for avalonia, which used the features of platform.

因此尝试以下方案：
Avalonia.HtmlRenderer，看起来还不错
https://github.com/AvaloniaUI/Avalonia.HtmlRenderer/tree/master
NuGet: https://www.nuget.org/packages/Avalonia.HtmlRenderer/11.0.0
 HTML Renderer AddFontFamily

_htmlPanel.Container.AddFontFamily(new FontFamily(
new Uri("avares://HtmlRenderer.Demo.Avalonia/fonts/CustomFont.ttf"),
"1 Smoothy DNA"));

上面代码Container.报错。改成下面的：

var f = new FontFamily(
new Uri("avares://AvaloniaAAA/Assets/Fonts/KaiTi.ttf"),
"KaiTi");

HtmlRender.AddFontFamily(f);

htmlPanel.Text = @"<p style=""font: 20px 'KaiTi'"">参数 <b><img src=""https://image.wjx.com/images/index/assessment.png""></b> sq</p><table border=""1"">
