Creating a multidimensional table

initTable1 = table('Size',[6,4],'VariableTypes',{'string','double','double','double'});
initTable2 = table('Size',[6,4],'VariableTypes',{'string','double','double','double'});
initTable3 = table('Size',[6,4],'VariableTypes',{'string','double','double','double'});

stackTable = {initTable1, initTable2, initTable3};
