The QTextTableFormat 类为表格提供格式化信息在 QTextDocument .
A table is a group of cells ordered into rows and columns. Each table contains at least one row and one column. Each cell contains a block. Tables in rich text documents are formatted using the properties defined in this class.
Tables are horizontally justified within their parent frame according to the table's alignment. This can be read with the alignment () function and set with setAlignment ().
Cells within the table are separated by cell spacing. The number of pixels between cells is set with setCellSpacing () and read with cellSpacing (). The contents of each cell is surrounded by cell padding. The number of pixels between each cell edge and its contents is set with setCellPadding () and read with cellPadding ().
The table's background color can be read with the background () function, and can be specified with setBackground (). The background color of each cell can be set independently, and will control the color of the cell within the padded area.
The table format also provides a way to constrain the widths of the columns in the table. Columns can be assigned a fixed width, a variable width, or a percentage of the available width (see QTextLength )。 columns () function returns the number of columns with constraints, and the columnWidthConstraints () function returns the constraints defined for the table. These quantities can also be set by calling setColumnWidthConstraints () with a vector containing new constraints. If no constraints are required, clearColumnWidthConstraints () can be used to remove them.

Sets the table's alignment .
另请参阅 alignment ().
Sets the cell padding for the table. This determines the distance between the border of a cell and its contents.
另请参阅 cellPadding ().
Sets the cell spacing for the table. This determines the distance between adjacent cells.
