Split Cell by Linebreak then Delimiter

I am having a problem to do both at the same time.

This is my sample data from a text file:

FirstName|LastName|Country
Jake|Abraham|US
Nigel|Brook|US
Mila|Niz|Canada

I pass those data to a variable and wanted to split it via '|' pipe delimiter and linebreak

content = regexp(content,'\|\r\n','split');

above outputs the structure I wanted but theres 1 mistake the cell never shift to next line it only continues to the first cell lines

    [ FirstName ][ LastName ][ Country ][    Jake   ][  Abraham ][    US   ][    Nigel  ][   Brook  ][    US   ][    Mila   ][    Niz   ][ Canada  ]

the output I was trying to accomplish is this:

    [ FirstName ][ LastName ][ Country ]
    [    Jake   ][  Abraham ][    US   ]
    [    Nigel  ][   Brook  ][    US   ]
    [    Mila   ][    Niz   ][ Canada  ]

so it will look right when I attached the cell variable to the uitable I wanted to attach the output data to the uitable.

I manage to do it using loop with this code:

container = {};
row = {};
content = regexp(content,'\r\n','split');
content = cellfun(@(x) regexp(x,'\|','split'), content, 'UniformOutput', false)';
content(end) = [];

for x = 1:length(content)
row = content{x};
container = [container ; row];
end

but it takes too much time to process 100k+ lines

is there a possible way to apply both split rule faster?
