答案1

导致您问题的原因是下表行：

AF: as fabricated, h: perpendicular to build direction, v: in build direction &       &       &       &       &       &       &  \\

替换为

\multicolumn{8}{l}{AF: as fabricated, h: perpendicular to build direction, v: in build direction}\\

您将获得所需的结果。但是，您的表格似乎是用某些表格生成器生成的，因此包含很多杂乱信息。为了获得进一步的帮助，您应该提供完整的小文档，其中序言中只有表格相关的包。到目前为止，我得到以下结果：

第一列和第二列之间的巨大空白是由 下方注释的宽度造成的\bottomrule。在下面的示例中，我将这些注释括在 中，该 宽度为 8 列。此外，我还删除了似乎源自表格生成器的multicolumn不必要的命令。\multicolumn{1}{l}

在以下示例中，我自由地做了一些修改：我使用包将threeparttable表格注释包含在间距更好的内容中。此外，我为“微观结构”列使用了包X中的灵活宽度列tabularx，这样表格就不会超出文本宽度。最后，我删除了第一列，并建议您将此信息包含在标题中，因为实际上并不需要此列。

一些注意事项：由于您的示例中没有包含 documentclass，而且我不知道文档的边距大小，因此表格可能适合或不适合（如上例所示）页面的边距。因此您可能需要进一步调整。您还应该重新考虑您使用的部分，\textcolor因为深灰色几乎与黑色文本难以区分。最后，您应该重新考虑最后三列内容的对齐方式。

答案3

除了 (a) 将最后一行包装在\multicolumn{8}{l}{...}指令中和 (b) 摆脱大量毫无意义的\multicolumn{1}{l}{...}包装器之外，您还应该 (c) 在自动数学模式下呈现最后三列和 (d) 努力更清晰地组织标题材料。下面显示的解决方案还使用环境tabular*而不是“基本”tabular环境，以确保表格占据整个可用宽度。

单独的评论（在下面显示的解决方案中未解决）：您可能还想问自己是否有必要使用\upalpha和\upbeta而不是“普通”\alpha和\beta字符。
