Java add tables, nested tables in Word

Table as a visual mode of communication and organization, ways to organize data, widely used in various occasions and in the documentation. Common forms can contain text, images and other elements, we can insert a picture when operating tables, nested tables, write text and table formatting styles. Hereinafter, created by the Java programming Word document form and the formatting operation, including setting the font, font size, font color, font weight, etc., provided the cell alignment, the background color of the cell, cell merging / splitting, form border style, insert pictures and more.
