你好，我希望我的表头看起来像这样：
因此，表格计数位于顶部中央，标题后面跟着描述。
我的当前输出如下所示：
请注意，用阿拉伯数字计数表格是完全没问题的。此外，显示的粗体标题应该与表格列表中显示的标题不同，因为它太长了。
我的代码目前如下所示：

我会为各种元素使用更好的标记。可以通过对格式以及和的定义进行操作来修改标题的布局\firstpart（\secondpart我展示了如何使用后者来获得较小的字体大小）。
该表是数字的，因此最好以数学模式输入条目。

注意。我删除了不必要的包并添加了showframe只是geometry为了在上下文中查看表格。

以下解决方案使用各种 LaTeX 包来实现您发布的既定目标（表格编号和主标题的单独居中）并修改表格材料本身的格式。
caption格式化标题的包；tabularx用于设置表格材料宽度的包（\textwidth这可确保表格的图例不会占用太多的垂直空间）；该
siunitx包将所有数字条目（前四个数据行除外）与其各自的小数点标记对齐。
