What is "elementw" and "Matrix"? All we see are "Table" and "A".
If you have a cell array called ca, and you have a logical column vector "A", you can remove cells from ca where A is 1 or true like this:
caNew = ca(A==0); % Extract cells where A=0 (i.e. remove cells where A=1).
Or, equivalently
caNew = ca; % Initialize
caNew(A) = []; % Remove cells where A=1

Even easier is to use logical indexing. No need for find():
Table(A==1,:)=[];
table is a built in function in MATLAB. Even though MATLAB is case sensitive, so table is different than table, it's a good idea not to use variable names that are the "same" as function names.
I could have told you this . . . if you'd been a little more careful about your question. For example you never mentioned the "Table" variable at all in your question. And you used the word "cell" in a non-MATLAB-ish way. Go here http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F for a very good discussion of cells in MATLAB.

That is what Image Analyst said nearly 5 years ago. https://www.mathworks.com/matlabcentral/answers/304242-how-can-i-delete-some-specific-rows-from-a-cell#comment_393354
