Resize QTableView vertical header in PyQt4?

Question

I need to reduce the size of the first column (column with vertical headers)

How to resize a vertical QTableView title in PyQt4?

I have very large headers and a small graphical interface to show this table, please help me!

I can resize all the columns, but could not determine the resizing of the vertical headers?

I have tried many things like:

self.tableView.setColumnWidth(0, 30)  // only able to change the data columns in table not headers

self.tableView.verticalHeader().setResizeMode(QHeaderView.Interactive)  //Able to change the height of headers but not width of them

I want to create headers that can be changed by the user , and does not depend on any other project parameters, such as window size, size of other columns ....

Can someone help me?
