Create a table from symbolic vectors

I would like to create a table from symbolic data. I have a vector where each component is a polynomial. I would like to have a table whose entries are these polynomials. When I use table command this happens
>> syms x1 x2 x3 x4 x5 x6
>> G=[x1, x2, x3, x4, x5, x6]
G =
[ x1, x2, x3, x4, x5, x6]
>> table(G)
ans =
G
_________
[1x6 sym]
>>

The table(var1, var2,...) function will create a table where the variables are the inputs var1, var2, ...
What you want is to have a table where each element (or column) is a variable, so use array2table:
T = array2table(G)

It is being stored that way, just not displayed that way:
>> T.G1
ans =
x1

G=sym('x',[1,6])
H=num2cell(G)
table(H{:})

This is a limitation on the display of tables. If you need to see the content of the columns you will need to do the formatting yourself. The table is properly formed, it just isn't displaying as you hope.

Farid, tables are meant to store "column-oriented heterogeneous data". That's not what you have, or at least not in your example. You have one symbolic variable, a 1x6 row vector. There's not much point in creating a 1x6 table, it just doesn't get you anywhere that your G variable doesn't already.
What are you really trying to achieve?

x = sym('x', [6, 2]);
y = string(x);
table(y(:,1), y(:,2), 'VariableNames', {'first_column', 'second_column'})

table(char(y(:,1)), char(y(:,2)), 'VariableNames', {'first_column', 'second_column'})
