The table control also has a QTableWidget, which inherits from QTableView. The main difference between QTableWidget and QTableView is that QTableView can use custom data model to display content, while QTableWidget can only use standard data model, and its cell data is realized through qtablewidgettitem object. In general, using QTableWidget can meet most of our requirements. In addition to the QTableView method, it can also use the methods shown in the following table:
| method | describe |
| setRowCount(int rows) | Set the number of rows of the table control; |
| setColumnCount(int column) | Set the number of columns of the table control; |
| setHorizontalHeaderLabels([str] labels) | Used to set the text displayed in multiple sections of the horizontal header in sequence at one time. This method has no return value. A section with a label set will automatically create the item corresponding to the section; |
| setVerticalHeaderLabels([str] labels) | Used to set the text displayed in multiple sections of the vertical header in sequence at one time. This method has no return value. A section with a label set will automatically create the item corresponding to the section; |
| setTextAlignment() | Set the alignment of the text in the cell; |
| currentColumn() | Get the subscript of the selected column; |
| currentRow() | Obtain the subscript of the selected row; |
| currentItem() | After getting the item, you can use the text() method to get the content; |
| selectedItems() | Get the list [qtablewidgettitem], and you can cycle to get the content value of each column; |
| item(int row, int column) | Get content with the subscripts of rows and columns. |
