Just as table cells are regular text shapes, table borders are just lines (a type of auto shape). However unlike cells, you do not work with the underlying shape in order to change a border. To change the appearance of a border you choose a cell or a rectangular set of cells, decide which borders for those cells you wish to update and then use the table border methods to access a border property (e.g. color, width, style, etc).

You can set the borders for a single cell or a collection of cells. You set the borders by changing the borders' properties, where the borders are specified by (a) the type of borders you wish, and (b) the applicable cell or cells. The border types are a set of predefined constants that represent the border formatting options available in PowerPoint. (Border type values are listed in the table below).

To set the border for a single cell use:

void setBorder(TextShape cell, int type, int property, java.lang.Object value)

To set the border for a rectangular collection of cells use:

void setBorder(java.util.Collection cells, int type, int property, java.lang.Object value)

To get the border for a cell, you get the border properties for that cell using:

java.lang.Object getBorder(int row, int column, int type, int property)

The library supports the following border types:

For example the following code snippet set a green border around an entire table.

Table table = ...;
table.setBorder(table.selectTable(), Table.BORDER_OUTER, ShapeProperties.LINE, Boolean.TRUE);
table.setBorder(table.selectTable(), Table.BORDER_OUTER, ShapeProperties.LINE_COLOR, Color.green);
