Each variable in a table can have a different data type and a different size with the one restriction that each variable must have the same number of rows. There are several ways to create tables and assign data to them. You can create tables from input arrays, preallocate tables and fill them in later, or import tables from text files or spreadsheets. If you want to control the import process beyond the options provided by the readtable function, such as defining how to handle missing data or errors, then create an import options object before importing the data.

The rows of a table can have names, but row names are not required. To access or modify table data, index into the rows and variables using either their names or numeric indices. Another way to access or modify table data is to open it in the Variables editor for graphical editing.
