how do i get the position(bottom) of dynamically changing rows of my gui table

So i have a table in my gui which get updated with different selections that i make in my screen . the gui table has different rows and columns, the rows increses with the selections i make in my screens , that means syntax ....Position( left, bottom, width , Height) the value of bottom changes everytime the selection is made . Now my gui table also has columns, the columns remains the same , i want to include a drop down list in one of my columns in the gui , so because the bottom value changes i cannot give a value in bottom the syntax position ( left, x, width,height)... so how can i get the value of the bottom positon in a changing table or row increasing table in gui. so as i can include a drop down list.

This line of code will return to you the number of rows in your table. Just perform it when you need to return the new length.

rows = length(x(:,1));

Where x is a variable that represents your matrix.
