**第二次编辑：我更改了标题以确保不会让任何人感到困惑。看到大家的评论后，我意识到我在哪里感到困惑。
- *制作所有文本的有效方法是什么
"\flushleft"？问题解决了。感谢@koleygr（参见第一个答案，评论 1） - *有什么有效的方法来“设置”表格中的所有元素的样式，而不是单独设置它们？问题解决了。同上（评论 2）。
- *创建多条新行的有效方法是什么？问题解决了。同上（评论 3）。还有更多问题需要解决：
- 我如何知道有多少英寸或厘米
\vspace？有经验吗？ - 当我写的时候
\documentclass[12pt]{article}，字体大小和 M$ Word 中的字体大小不同吗？因为我是根据教授给我的文档重新设计轮子，但字体大小并不完全相同。 - 如果里面
\(\)有一些我不想用斜体显示的文字，我\text{}每次都必须写吗？
大家好！我这个学期结束后就要上大学了。我是数学专业的，我想提前学习 LaTeX。我已经学习 LaTeX 有一段时间了，这是我第一次用 LaTeX 写经济学作业。
你们觉得这段代码怎么样？有什么需要改进的吗？
我在写作时注意到的一件事是，我创建的表格与上面的其他文本相比略有偏移。有什么办法可以解决这个问题吗？
向大家致以最良好的祝愿。
以下是我的结果：
