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.

Thank you. The code works now.

Filefolder = find(table2array(Folderlinks)~="")
