We have table，Why we use timetable？

What is the difficience between the table and timetable？

Timetable Documentation

“timetable is a type of table that associates a time with each row. Like tables, timetables store column-oriented data variables that can have different data types and sizes as long as they have the same number of rows. In addition, timetables provide time-specific functions to align, combine, and perform calculations with timestamped data in one or more timetables.”-----------------I have a table that associates a time with each row. temp is table，The 4th column is the datetime Var（varname is ‘time’），so，I can run this code to find row that date is 2008-01-03

temp((temp{:,4}==datetime('2008-01-03')),:)

I can sort by time

sortrows(temp,'Time')

Is there anything that a timetalb can do, but table cannot? What job must be done using a timetabl instead of a table?

Almost all the functions that tables can use ，timetable can use too. Like:removevars vartype addprop………………

It looks like timetables offer additional functionality helpful for dealing with time histories of data: Timetables

[Steven Lord]

That is correct. You can retime a timetable or synchronize two or more timetables, which you cannot do with tables.

[Eric Sofen]

And you can subscript a timetable directly by time or use subscripting helpers like timerange to select rows between two times, rather than using logical indexing (rather complicated logical indexing in the case of timerange).

Some of the topics in the timetable doc section can give you a broader sense of timetable's unique capabilities and purpose:

Clean Timetable with Missing, Duplicate, or Nonuniform Times

Resample and Aggregate Data in Timetable

Combine Timetables and Synchronize Their Data

Retime and Synchronize Timetable Variables Using Different Methods

Select Times in Timetable

It would be helpful if the Descriptions section of doc page for timetable had a link to the Timetables doc (linked in your comment and my answer), instead of it being buried down in the Tips section.
