table2array() . Or, if the table is all numeric, you can give the table name and then {:, :} such as
mytable{:,:}

The code I posted does that. Table objects are always 2 dimensional in MATLAB and for two dimensions the terms array and matrix are the same thing.

As an alternative, you can convert a table to an array by using the syntax “T{:,:}”, where “T” is the table. This syntax is the equivalent of “table2array”.
All variables in the table must have sizes and data types that allow them to be horizontally concatenated. For example, if all variables in “T” are numeric, then “table2array” returns a numeric array.

I tried both table2array and “T{:,:}” but it changes the values inside the table from 0.7 to 1. Is there a way I can keep the original values, I tried using double datatype but it doesn't work

table2array() converting 0.7 to 1 could happen if the table is mixed data type including at least one integer data type such as uint8 . Please check
unique( varfun(@class, T, 'outputformat', 'cell') )

Another alternative to convert table to matrix is to use a syntax: M=T.Var, e.g.
T = table(magic(5))
M=T.Var1

What can I do if I have N var, with random names, inside a table that imports from excel, this table can vary.
that is, the method of putting T. "name var" is not possible if I have N quantity of varials with N different names

You can use variable indexes if the indexes are constant.
If the variable order is not constant, then you can take T.Properties.VariableNames and extract whatever subset of those you want and sort them in whatever you want. Then you can loop doing dynamic field names.
Example, selecting variables that start with "run"
names = T.Properties.VariableNames;
runvars = sort(names(startsWith(names, 'run')));
nrun = length(runvars);
for varidx = 1 : nrun
thisvarname = runvars{varidx};
thiscontent = T.(thisvarname);
stuff here
end
