Just get the coordinates

[rows, columns] = find(grayImage < 128);

Then find the max and min:

row1 = min(rows);
row2 = max(rows);
% Find average column
meanColumn = int32(mean(columns));

Then draw the line

grayImage(row1:row2, meanColumn) = 0;

What "cells"? Do you mean pixels? And what does "delete" mean to you, keeping in mind that an image must remain rectangular. Do you just want to replace them (not delete them) with white pixels? Then why not just draw the line on a completely new white image

whiteImage = 255 * ones(rows, columns, 'uint8');
whiteImage(row1:row2, meanColumn) = 0;
