The border properties in a table's cell style control the display of the gridlines that divide the table into cells. The Cell and Contents sections of the Properties Inspector are used to control the border styles, text formatting, and the size of the cells. Table styles control the appearance of a table and all of the cells contained in the table, but you can override the style of individual cells. If you have a table style saved in your drawing, you can assign it to the table using the Table Style property under the Table section.
To display all of the table properties in the Properties Inspector, click All above the Object drop-down list. When you select a table, you can change the appearance of the a table under the Table and Table Breaks sections of the Properties Inspector and Table visor.
You can edit the properties of a table and individual cells using the Properties Inspector. Note: AutoCAD 2022 for Mac does not support the ability to create or modify table and cell styles.
