MATLAB: Undefined function ‘ne’ for input arguments of type ‘table’.

undefined function 'ne' for input arguments of type 'table'.

I am having some trouble with updating a table as I first am extracting date from the 8th column, then I try to find data within that column that don't equal "". Such as:
columnData=CopyofEGIYieldDataJuly202073020(2056:2098,:)
Folderlinks=columnData(:,8)
% Fstr=string(Folderlinks)
    Filefolder=find(Folderlinks~="")
    EGIdataMike=columnData(Filefolder,:)
But this results in 
    Undefined function 'ne' for input arguments of type 'table'.
Error in Untitled4 (line 8)
    Filefolder=find(Folderlinks~="")
I'm trying to get the data to where it is not just the "" like this:
into a new table with the same columns. So it would then cut down the number of rows as I want to look at the dat where in that column it is not just "".
Any suggestions or application of corrections?

If you want the data as a smaller table, index into the larger table with parentheses.
Folderlinks=columnData(:,8) % Folderlinks is a table array
If you want the data as a string array (pulling the data out of its table container) index into the larger table with curly braces.
FolderlinksString = columnData{:, 8} % FolderlinksString is a string array
The not-equal operator ~= is defined for string arrays but not for table arrays.
