(1) Make an ordinary table first. Open the menu "Table-Insert Table", select the number of columns "3" and the number of rows "4", and a bordered table with three columns and four rows will appear in the document. Enter the content, and then merge the cells of all columns in the table except the first row (select the cells to be merged, and right-click to select the merged cells. (2) Move the mouse to the upper left corner of the table. When the four-way arrow appears, select the table (point black), open the menu "Format-Borders and Shading", and select "None" in the settings to cancel all borders of the table. (3) Select a thicker line from the line width drop-down list, such as 1 and 1/2 points, and add "top", "bottom" and "middle" edge lines to the table among the various solid edge lines on the right (note: selecting the middle edge line does not mean adding only one line in the middle, but adding the original line in the middle). accomplish
