You can get something like this :
The + button allow the user to add a new line, and the - button remove the last line. It's possible to remove the selected line with the selectedIndexes() method from the QAbstractItemView Class.
The Get Value button print a dictionary in the python console with an element for each row and a list with all the values.
{'layer_1': ['connexions', 'id', 'first_layer', 'True'], 'layer_2': ['lineaire_spirit_m', 'fid', 'second_layer', 'False']}
Here is the full code, it works in the QGIS Python Console :
from PyQt5.QtWidgets import QPushButton, QTableWidget, QComboBox, QDialog
class Dialog(QDialog):

# Create the dialog

self.tableWidget.setColumnCount(4) # Number of columns.
self.tableWidget.setRowCount(0) # Number of rows.
self.tableWidget.setHorizontalHeaderLabels(["Layer", "Field", "String", "Bool"]) # Set labels for columns.
self.add_layer() # Add the first row.
# Create the add layer button
button_plus = QPushButton(self)
button_plus.setText("+") # Set label of the button.
button_plus.setGeometry(30, 50, 50, 50) # Set the size of the button.
button_plus.clicked.connect(self.add_layer) # Connect the button to a function.
# Create the remove layer button
button_minus = QPushButton(self)
button_minus.setText("-") # Set label of the button.
button_minus.setGeometry(30, 150, 50, 50) # Set the size of the button.
button_minus.clicked.connect(self.remove_layer) # Connect the button to a function.
# Create the get value button
button_result = QPushButton(self)
button_result.setText("Get Value") # Set label of the button.
button_result.setGeometry(10, 250, 100, 50) # Set the size of the button.
button_result.clicked.connect(self.get_result) # Connect the button to a function.

else:
