装饰线（大部分）包含在边界框内

Question

这是一个伟大的起点彩色盒子包装。它有黑色和黄绿色线条的所有装饰；如果您有足够的耐心，可以以相同的方式添加其他背景图形，在您决定它们是否以及如何适应框架尺寸之后。

在下面的例子中，我定义了一个tcolorbox名为的皮肤ornamented，一个同名的样式，skin=ornamented以及一些其他设置（其中包括屏幕截图中框标题字体的小型大写字母形状），以及一个名为的环境ornamentedbox。此环境输出tcolorbox使用样式的ornamented。ornamentedbox环境有一个可选参数：您可以tcolorbox在那里插入选项，这些选项可能会覆盖的默认设置ornamentedbox。

当然，你可以tabular在环境中放入数组、数学、图像等。毕竟，ornamentedbox它是一个。:-)tcolorbox

我建议使用两种代码变体，它们的区别在于装饰线相对于边界框的定位以及框周围的空间处理。我更喜欢第二种，因为在我看来，它可以更好地调整框内的垂直间距。

装饰线（大部分）包含在边界框内

在这个变体中，除了左侧和右侧的非常小的细节外，我们确保所有装饰规则都是里面的边界框ornamentedbox（见下面的屏幕截图，其中边界框用红色绘制）。这通常使得相对于框外部的内容的定位更容易，因为不存在与框上方或下方的内容重叠的风险——但最理想的变体最终取决于您想要什么。

下面是上例中第一个框的截图，其边界框为红色（通过该show bounding box选项可见）：

细节：

装饰线超出了边界框

在第二种变体中，装饰线在所有侧面都延伸到边界框之外一点。在某些情况下，这可能很有用（例如，对于一个或多个页边距旁边的框，这种行为可能是可取的）。但如果不小心，这显然会导致与附近内容重叠。我通过添加跳过来处理这个问题：这些是出现时会自动消失的空格（水平或垂直）：

位于行首或行末，为水平类型；
位于页面的开头或结尾，用于垂直类型。

因此，当框旁边有内容时，跳过会阻止框旁边的内容与装饰线重叠；但是当框靠在其中一个页边距上时，相应的跳过会消失，并且此侧的装饰会略微超出页边距通常允许的范围（即，允许装饰在页边距中突出）。

如上所述，使用此代码变体，所有装饰线都会故意延伸到边界框外面一点点（使用该show bounding box选项获得的图像）：

细节：

请注意，我上面提到的跳过的位置外部用红色表示的边界框（在它旁边），准确地告诉 TeX 超出边界框的装饰所占用的空间。当这些跳过出现在行的开头或结尾（对于水平跳过）或页面的开头或结尾（对于垂直跳过）时，TeX 会自动丢弃这些跳过。

装饰环境`tabular`

在上一个示例中，我定义了一个名为的环境，ornamentedtabular该环境将很好地包装tabular在内，ornamentedbox并添加了一些内容，例如交替颜色。如代码和屏幕截图所示，它允许人们轻松获得类似于您发布的图片中的表格演示。此环境也可以与的第一个变体一起使用ornamentedbox。

Answer 1

这是一个伟大的起点彩色盒子包装。它有黑色和黄绿色线条的所有装饰；如果您有足够的耐心，可以以相同的方式添加其他背景图形，在您决定它们是否以及如何适应框架尺寸之后。

在下面的例子中，我定义了一个tcolorbox名为的皮肤ornamented，一个同名的样式，skin=ornamented以及一些其他设置（其中包括屏幕截图中框标题字体的小型大写字母形状），以及一个名为的环境ornamentedbox。此环境输出tcolorbox使用样式的ornamented。ornamentedbox环境有一个可选参数：您可以tcolorbox在那里插入选项，这些选项可能会覆盖的默认设置ornamentedbox。

当然，你可以tabular在环境中放入数组、数学、图像等。毕竟，ornamentedbox它是一个。:-)tcolorbox

我建议使用两种代码变体，它们的区别在于装饰线相对于边界框的定位以及框周围的空间处理。我更喜欢第二种，因为在我看来，它可以更好地调整框内的垂直间距。

装饰线（大部分）包含在边界框内

在这个变体中，除了左侧和右侧的非常小的细节外，我们确保所有装饰规则都是里面的边界框ornamentedbox（见下面的屏幕截图，其中边界框用红色绘制）。这通常使得相对于框外部的内容的定位更容易，因为不存在与框上方或下方的内容重叠的风险——但最理想的变体最终取决于您想要什么。

下面是上例中第一个框的截图，其边界框为红色（通过该show bounding box选项可见）：

细节：

装饰线超出了边界框

在第二种变体中，装饰线在所有侧面都延伸到边界框之外一点。在某些情况下，这可能很有用（例如，对于一个或多个页边距旁边的框，这种行为可能是可取的）。但如果不小心，这显然会导致与附近内容重叠。我通过添加跳过来处理这个问题：这些是出现时会自动消失的空格（水平或垂直）：

位于行首或行末，为水平类型；
位于页面的开头或结尾，用于垂直类型。

因此，当框旁边有内容时，跳过会阻止框旁边的内容与装饰线重叠；但是当框靠在其中一个页边距上时，相应的跳过会消失，并且此侧的装饰会略微超出页边距通常允许的范围（即，允许装饰在页边距中突出）。
