how to save a table to .asc file

hello I used the following code to generate a table which I want to save as a text, excel and asc file. I have managed to do the first to but I can't seem to convert it to a asc file. The table is generated in the correct format as i can convert the text file by manually saving it as '.asc' Essentially the asc file will be imported in a CAD software. Any suggestions? Thanks

blade_L_e={X_guides,blade(1).L_e(:,1),Y_guides,blade(1).L_e(:,2),Z_guides,blade(1).L_e(:,3)}; %table in X,coordinate,Y,coordinate,Z,coordinate
tab_L_e = table(blade_L_e{:});
writetable(tab_L_e,'L_e.txt', 'WriteVariableNames', false,'Delimiter',' ')
writetable(tab_L_e,'L_e.xlsx', 'WriteVariableNames', false)

writetable(tab_L_e, 'L_e.asc', 'WriteVariableNames', false, 'Delimiter', ' ', 'Filetype', 'text')
