\section{Introduction}
His grandfather, Bhuramal Das Chaudhary, migrated to Nepal from Rajasthan in the 19th century. After his arrival at the age of 20 he started a textile business in the 1930s.[8] A few years later, after the 1934 Nepal–Bihar earthquake, he became the first in Nepal to start a formally registered clothing company.[8] His father, Lunkaran Das Chaudhary, continued to develop the textile business, and also established international-trading houses, and a construction company.[8] In 1968 Lunkaran Das Chaudhary founded Arun Emporium, a retail store which was his most successful enterprise.[8] At the age of eighteen, Binod Chaudhary was about to head towards India to study chartered accountancy however his father was diagnosed with heart disease, the doctor told him his father could not continue to run the family business.[13] As he was the eldest son in the family he stepped into the family business.[13] He told The Telegraph, "My life was overnight changed completely. I did not have a choice at all. But it has made me a tougher man."[13] He also stated "I would have liked to study further but I was required to do my duty" In an interview with Hong Kong Tatler.[14]
He considered importing Japanese Suzuki cars to Nepal. He says, "Suzuki did not trust me as I was a young clothes trader. I convinced them. They gave me a trial dealership along with four others to sell Suzuki in Nepal. Whoever sold most cars in six months would get the dealership."[15]
His first independent business was in 1973, it was a discothèque company called Copper Floor.[8] The company was a huge success, because of the many wealthy and powerful people who visited the club.[8] In 1979 Chaudhary made a deal with Japanese electronic firm National Panasonic, which was his first multinational deal.[8] The deal gave him the right to import National Panasonic's parts to make radios throughout Nepal.[8]His grandfather, Bhuramal Das Chaudhary, migrated to Nepal from Rajasthan in the 19th century.

答案1
如果您希望表格材料“浮动”到列的顶部，则必须将其包裹在“浮动对象”中，例如环境table。为了确保它被放置在列的顶部，您需要放置说明符[t!]，即您需要写入\begin{table}[t!]。
顺便说一句，除非您以某种方式修改了c列类型以开始接受参数，否则我认为这无法c{1.7cm}c{3cm}c{3cm}c{3cm}成功编译。我会改用普通的c列类型。

答案2
\begin{table}[t]...\end{table}表格周围缺少，这意味着顶部是唯一允许的选项，或者\begin{table*}....\end{table*}表格应该跨越两列\maketitle应该在文档里面摘要也需要包含在文档中
你必须
