<h2>Detailed Description</h2>
158
<p>The QTableWidget class provides an item-based table view with a default model.</p>
159
<p>Table widgets provide standard table display facilities for applications. The items in a QTableWidget are provided by <a href="qtablewidgetitem.html">QTableWidgetItem</a>.</p>
160
<p>If you want a table that uses your own data model you should use <a href="qtableview.html">QTableView</a> rather than this class.</p>
161
<p>Table widgets can be constructed with the required numbers of rows and columns:</p>
162
<pre> tableWidget = new QTableWidget(12, 3, this);</pre>
163
<p>Alternatively, tables can be constructed without a given size and resized later:</p>
164
<pre> tableWidget = new QTableWidget(this);
165
tableWidget->setRowCount(10);
166
tableWidget->setColumnCount(5);</pre>
167
<p>Items are created ouside the table (with no parent widget) and inserted into the table with <a href="qtablewidget.html#setItem">setItem</a>():</p>
168
<pre> QTableWidgetItem *newItem = new QTableWidgetItem(tr("%1").arg(
169
(row+1)*(column+1)));
170
tableWidget->setItem(row, column, newItem);</pre>
171
<p>Tables can be given both horizontal and vertical headers. The simplest way to create the headers is to supply a list of strings to the <a href="qtablewidget.html#setHorizontalHeaderLabels">setHorizontalHeaderLabels</a>() and <a href="qtablewidget.html#setVerticalHeaderLabels">setVerticalHeaderLabels</a>() functions. These will provide simple textual headers for the table's columns and rows. More sophisticated headers can be created from existing table items that are usually constructed outside the table. For example, we can construct a table item with an icon and aligned text, and use it as the header for a particular column:</p>
172
<pre> QTableWidgetItem *cubesHeaderItem = new QTableWidgetItem(tr("Cubes"));
173
cubesHeaderItem->setIcon(QIcon(QPixmap(":/Images/cubed.png")));
174
cubesHeaderItem->setTextAlignment(Qt::AlignVCenter);</pre>
175
<p>The number of rows in the table can be found with <a href="qtablewidget.html#rowCount-prop">rowCount</a>(), and the number of columns with <a href="qtablewidget.html#columnCount-prop">columnCount</a>(). The table can be cleared with the <a href="qtablewidget.html#clear">clear</a>() function.</p>
