Experimental measurement and calculation data are the core contents of scientific papers. As one of the main forms of data expression, tables are widely used because of their clear function of quantitatively expressing quantitative information. The three-line table is concise in form, clear in function and easy to read, so it is recommended to be used in scientific papers.

Three-line tables usually have only three lines, namely, top line, bottom line and column line (see figure, note: there is no vertical line). The upper and lower lines are thick lines and the column lines are thin lines. Of course, a three-line meter doesn't necessarily have only three lines, and auxiliary lines can be added when necessary, but no matter how many auxiliary lines are added, it is still called a three-line meter. The elements of three-line table include: preface, title, item column, text and comments.

The border of a three-line table often has only three horizontal lines, namely, the top line, the bottom line and the column line, and there is no vertical line. Components also include: preface, title, header, item column (subject column), category column (object column), table body (character column), and footnotes if necessary. Header, item column (subject column), category column (object column) and table body (character column) constitute the table body, which is the main body of the table.

The border, top line and bottom line of the three-line table are thick lines, and the column lines are thin lines. If necessary, you can add auxiliary lines. But no matter how many auxiliary lines are added, it is still called a three-line table.

2. Features

The frame structure of three-wire watch is a remarkable feature that distinguishes it from other watches. Under this structure, it shows the inherent essential characteristics of clear function, conciseness, simplicity and easy reading.
