57 \brief The QTextTableCell class represents the properties of a -

58 cell in a QTextTable. -

59 \inmodule QtGui -

60 -

61 \ingroup richtext-processing -

62 -

63 Table cells are pieces of document structure that belong to a table. -

64 The table orders cells into particular rows and columns; cells can -

65 also span multiple columns and rows. -

66 -

67 Cells are usually created when a table is inserted into a document with -

68 QTextCursor::insertTable(), but they are also created and destroyed when -

69 a table is resized. -

70 -

71 Cells contain information about their location in a table; you can -

72 obtain the row() and column() numbers of a cell, and its rowSpan() -

73 and columnSpan(). -

74 -

75 The format() of a cell describes the default character format of its -

76 contents. The firstCursorPosition() and lastCursorPosition() functions -

77 are used to obtain the extent of the cell in the document. -

110 QTextCharFormat format = cell.format(); -

111 format.setBackground(Qt::blue); -

112 cell.setFormat(format); -

115 to use QTextTable::mergeCells and QTextTable::splitCell instead. -

500 \brief The QTextTable class represents a table in a QTextDocument. -

501 \inmodule QtGui -

502 -

503 \ingroup richtext-processing -

504 -

505 A table is a group of cells ordered into rows and columns. Each table -

506 contains at least one row and one column. Each cell contains a block, and -

507 is surrounded by a frame. -

508 -

509 Tables are usually created and inserted into a document with the -

510 QTextCursor::insertTable() function. -

511 For example, we can insert a table with three rows and two columns at the -

512 current cursor position in an editor using the following lines of code: -

513 -

514 \snippet textdocument-tables/mainwindow.cpp 1 -

515 \codeline -

516 \snippet textdocument-tables/mainwindow.cpp 3 -

517 -

518 The table format is either defined when the table is created or changed -

519 later with setFormat(). -

520 -

521 The table currently being edited by the cursor is found with -

522 QTextCursor::currentTable(). This allows its format or dimensions to be -

523 changed after it has been inserted into a document. -

524 -

525 A table's size can be changed with resize(), or by using -

526 insertRows(), insertColumns(), removeRows(), or removeColumns(). -

527 Use cellAt() to retrieve table cells. -

528 -

529 The starting and ending positions of table rows can be found by moving -

530 a cursor within a table, and using the rowStart() and rowEnd() functions -

531 to obtain cursors at the start and end of each row. -

532 -

533 Rows and columns within a QTextTable can be merged and split using -

534 the mergeCells() and splitCell() functions. However, only cells that span multiple -

535 rows or columns can be split. (Merging or splitting does not increase or decrease -

536 the number of rows and columns.) -

537 -

538 Note that if you have merged multiple columns and rows into one cell, you will not -

539 be able to split the merged cell into new cells spanning over more than one row -

540 or column. To be able to split cells spanning over several rows and columns you -

541 need to do this over several iterations. -

542 -

543 \table 80% -

544 \row -

545 \li \inlineimage texttable-split.png Original Table -

546 \li Suppose we have a 2x3 table of names and addresses. To merge both -

547 columns in the first row we invoke mergeCells() with \a row = 0, -

548 \a column = 0, \a numRows = 1 and \a numColumns = 2. -
