MATLAB provides functions for conversions between numeric arrays, strings and character arrays, and categorical, datetime, and duration arrays. I have very long arrays of symbolic variables which I need to convert to cell arrays of strings: For example, turning this: syms x y uq = [x y u] into this: qs = { 'x' 'y' 'u' } Best practice is to avoid creating table or timetable variables that are character arrays. Also, you can convert between the data types that group data in containers, such as cell arrays, structures, tables, and timetables. Conversion from cell array to character string is a matter of de-referencing each of the cell array entries to get the already-contained character string, and building up rows of a char array, with the rows padded (with blanks) to the length of the longest string. It can have any length and if the string array has one element then it is known as string scalar.

Each column of X becomes a variable of TT.The time values in rowTimes label the rows of the timetable.TT is an M-by-N timetable.. For more information on creating and using timetables, see Timetables. That's the advantage of tables; they can handle disparate data types as a group while arrays must be wholly of one class (excepting cell arrays which are useful but not needed here and would just compound the dereferencing).
