我正在尝试使所有表格的字体大小相同。我有不同的表格，标题和列数和行数不同，这导致字体大小因情况而异。我尝试了在互联网上找到的不同方法，但尚未成功。
以下是一个例子：

前两个表的输出是：
答案1
1）如果需要，不要缩放表格，而只是减小字体从\normalsize标准较小尺寸：\small或者\footnotesize但请不要超出这个范围。请注意，这不仅会产生一致的尺寸，而且还会产生良好字体中的适当字形（例如，当缩放到相同尺寸时， a{\huge Q}将与 a 完全不同{\tiny Q}）。顺便说一句，在表 1 和表 2 中，这不是必需的，假设文章的默认边距（抱歉，我没有该类ociamthesis）
2) 如果这还不够（表格 3 和 4），或者（可能更好）尝试通过重新设计表格来获得水平空间和/或调整列宽并允许在单元格中换行。使用p列、m列（array包）和tabularx包tabulary对于调整表格非常有用。
3) 最后与问题无关，但要避免使用垂直线和多余的水平线，使用更好的水平线（包 booktabs）并尝试使用siunitx包对齐/格式化数字。MWE 还展示了其他一些小技巧，以便在有/没有显式数学环境（新列 M）的情况下获得更好的间距\pm。我将标题移到前面，因为大多数期刊都使用这种风格，但显然是可选的。（四个表格位于同一个浮动中只是为了方便将 MWE 保持在单个页面中。）
