Detailed Description
The QTextTable class represents a table in a 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, and is surrounded by a frame.
Tables are usually created and inserted into a document with the QTextCursor::insertTable() function. For example, we can insert a table with three rows and two columns at the current cursor position in an editor using the following lines of code:
QTextCursor cursor(editor->textCursor());
cursor.movePosition(QTextCursor::Start);
QTextTable *table = cursor.insertTable(rows, columns, tableFormat);
The table format is either defined when the table is created or changed later with setFormat().
The table currently being edited by the cursor is found with QTextCursor::currentTable(). This allows its format or dimensions to be changed after it has been inserted into a document.
A table's size can be changed with resize(), or by using insertRows(), insertColumns(), removeRows(), or removeColumns(). Use cellAt() to retrieve table cells.
The starting and ending positions of table rows can be found by moving a cursor within a table, and using the rowStart() and rowEnd() functions to obtain cursors at the start and end of each row.
