Help using grpstats function to get number of occurances per row on a table.

I have the following table (4 rows, column names are simply "Col1", "Col2" and so on), for which I'd like to apply grpstats function on.
'China','Hong Kong', '', 'China'
'', 'Switzerland', '', 'Switzerland'
'United States', 'Ireland', '', 'United States'
'Finland', 'Finland', 'Sweden', ''
What I would like to do is to get is the most repeated observation across the rows, using such function without needing to use a combination of accumaray, categorical and unique.
How may I use it? Can you help please?

My answer uses groupcounts which does not rely on having the stats & machine learning toolbox, unlike grpstats.

C = {'China','Hong Kong', '', 'China'
'', 'Switzerland', '', 'Switzerland'
'United States', 'Ireland', '', 'United States'
'Finland', 'Finland', 'Sweden', ''};
rowNum = repmat((1:size(C,1))', 1, size(C,2));
T = table(C(:),rowNum(:),'VariableNames',{'Country','RowNum'});
B = groupcounts(T,{'RowNum','Country'})
