wish help you to fix your issue You have to enable the wordwrap in the QTextDocument in addition to setting the sectionResizeMode of the vertical header to QHeaderView::ResizeToContents:
code :
import sys
from PyQt5 import QtCore, QtGui, QtWidgets

class HighlightDelegate(QtWidgets.QStyledItemDelegate):
    def __init__(self, parent=None):
        super(HighlightDelegate, self).__init__(parent)
        self._filters = []
        self._wordwrap = False
        self.doc = QtGui.QTextDocument(self)

    def paint(self, painter, option, index):
        options = QtWidgets.QStyleOptionViewItem(option)
        self.initStyleOption(options, index)

        if self._wordwrap:
        options.text = ""

        style = QApplication.style() if options.widget is None else options.widget.style()
        style.drawControl(QtWidgets.QStyle.CE_ItemViewItem, options, painter)

        if self._wordwrap:
            painter.translate(options.rect.left(), options.rect.top())
            clip = QtCore.QRectF(QtCore.QPointF(), QtCore.QSizeF(options.rect.size()))
            self.doc.drawContents(painter, clip)
            ctx = QtGui.QAbstractTextDocumentLayout.PaintContext()
            if option.state & QtWidgets.QStyle.State_Selected:
                ctx.palette.setColor(QtGui.QPalette.Text, option.palette.color(
                    QtGui.QPalette.Active, QtGui.QPalette.HighlightedText))

            if index.column() != 0:

            constant = 4
            margin = (option.rect.height() - options.fontMetrics.height()) // 2
            margin = margin - constant

I think the issue was by ths following , You might also find it more concise and easier to use the output of the range (or xrange) as the indexes for your tableWidget.item call rather than worrying about incrementing your own counters. You might be using the sheet itself in other places in code, but if you're not, it would save you some memory to not assign the sheet to be an attribute variable of your class:
code :
def savefile(self):
    filename = unicode(QtGui.QFileDialog.getSaveFileName(self, 'Save File', '', ".xls(*.xls)"))    
    wbk = xlwt.Workbook()
    sheet = wbk.add_sheet("sheet", cell_overwrite_ok=True)

def add2(self, sheet):
    for currentColumn in range(self.tableWidget.columnCount()):
        for currentRow in range(self.tableWidget.rowCount()):
                teext = str(self.tableWidget.item(currentRow, currentColumn).text()
                sheet.write(currentRow, currentColumn, teext)
            except AttributeError:

hope this fix your issue I use following code to put a checkbox in the 9th column of my QTableWidget , One way to do it would be:
code :
from PyQt4 import QtGui, QtCore

class Window(QtGui.QWidget):
    def __init__(self, rows, columns):
        self.table = QtGui.QTableWidget(rows, columns, self)
        for column in range(columns):
            for row in range(rows):
                item = QtGui.QTableWidgetItem('Text%d' % row)
                if row % 2:
                    item.setFlags(QtCore.Qt.ItemIsUserCheckable |
                self.table.setItem(row, column, item)
        layout = QtGui.QVBoxLayout(self)
        self._list = []

    def handleItemClicked(self, item):
        if item.checkState() == QtCore.Qt.Checked:
            print('"%s" Checked' % item.text())
            print('"%s" Clicked' % item.text())

if __name__ == '__main__':

    import sys
    app = QtGui.QApplication(sys.argv)
    window = Window(6, 3)
    window.resize(350, 300)

Hope this helps I am working on a small library application. I am getting data from an excel sheet. And then sent to qtablewidget. , I solved myself. Here is the solution:
code :
liste = []
    for i in range(34):
        liste.append(self.ui.tableWidget.item(self.ui.tableWidget.currentRow(), i).text())

it fixes the issue The issue seems to stem from the fact that the value for option.rect.width() passed into QStyledItemDelegate.sizeHint() is -1. This is obviously bogus!
I've solved this by storing the width in the model from within the paint() method and accessing this from sizeHint().
code :
index.model().setData(index, option.rect.width(), QtCore.Qt.UserRole+1)
width = index.model().data(index, QtCore.Qt.UserRole+1)
if not width:
    width = 20

Any of those help add {your table}.table.horizontalHeader().setStretchLastSection(True) and/or {your table}.verticalHeader().setStretchLastSection(True)
code :
import sys

from PyQt4 import QtGui
from PyQt4 import QtCore

class Window(QtGui.QWidget):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent=parent)
        QtGui.QTableWidget.setMinimumSize(self, 500, 500)
        QtGui.QTableWidget.setWindowTitle(self, "Custom table widget")
        self.table = QtGui.QTableWidget()
        rowf = 3
        self.table.setHorizontalHeaderItem(0, QtGui.QTableWidgetItem("col1"))
        self.table.setHorizontalHeaderItem(1, QtGui.QTableWidgetItem("col2"))
        self.table.setHorizontalHeaderItem(2, QtGui.QTableWidgetItem("col3"))
        # self.table.verticalHeader().setStretchLastSection(True)

        self.buttonBox = QtGui.QDialogButtonBox(self)
        self.buttonBox.setStandardButtons(QtGui.QDialogButtonBox.Cancel | QtGui.QDialogButtonBox.Ok)

        self.verticalLayout = QtGui.QVBoxLayout(self)

    w = Window()
