如何在 FlowDocument 中水平居中表格或列表？

Question

下面是来自默认 WPF 应用程序的 MainWindow.xaml 的示例代码。文档中的第一个和最后一个“块”是段落，中间的“块”是表格。表格始终显示在其列的左边缘，表格右侧的区域为空白。我想将桌子放在这个空间的中心。

我尝试过将表格放入“部分”、“段落”等中，但没有任何运气。段落内的浮动框可以工作，但随后表格会流入下一个段落。也许我可以通过在左侧和右侧使用两个空列并通过某种方式动态计算它们的宽度来做到这一点，但这看起来有点矫枉过正。

谢谢 吉瓦卡

            <Paragraph>The moons of Saturn are numerous and diverse, ranging from tiny moonlets less than 1 kilometre across, to the enormous Titan, which is larger than the planet Mercury. Saturn has 62 moons with confirmed orbits, fifty-three of which have names, and only thirteen of which have diameters larger than 50 kilometres. Saturn has seven moons that are large enough to become spherical, and dense rings with complex orbital motions of their own. Particularly notable among Saturn's moons are Titan, the second largest moon in the Solar System, with a nitrogen-rich Earth-like atmosphere and a landscape including hydrocarbon lakes and dry river networks, and Enceladus, which emits jets of gas and dust and may harbor liquid water under its south pole region.</Paragraph>

            <Paragraph>Twenty-four of Saturn's moons are regular satellites; they have prograde orbits not greatly inclined to Saturn's equatorial plane. They include the seven major satellites, four small moons which exist in a Trojan orbit with larger moons, two mutually co-orbital moons and two moons which act as shepherds of Saturn's F Ring. Two other known regular satellites orbit within gaps in Saturn's rings. The relatively large Hyperion is locked in a resonance with Titan. The remaining regular moons orbit near the outer edge of the A Ring, within G Ring and between the major moons Mimas and Enceladus. The regular satellites are traditionally named after Titans and Titanesses or other figures associated with the mythological Saturn.</Paragraph>

有一个名为 Horizo​​ntalAlignment 的 WPF 元素属性，您希望将感兴趣的元素包围在容器内（例如网格或边框），并将该属性设置为 Center WPF 会执行其余操作魔法。
