How to fill MATLAB table with .Net char array?

In the code below I get an array of chars from .Net library(the array isn't empty and has all needed data). Then I want to convert it to cells and pass to the table. For now, the table filled only with one first character.

dict = WordStatLib.Program.dict;
arrKeys = NET.invokeGenericMethod('System.Linq.Enumerable', 'ToArray',{'System.Char'}, dict.Keys);
keysAsCell = num2cell(arrKeys);

table = findobj('Tag','FirstTable');
table.Data = keysAsCell;
