You can use either syntax to increase the size of a table by assigning rows beyond the end of the
table. If necessary, missing rows are filled in with default values.

Convert Variables to Tables
You can convert variables that have other data types to tables. Cell arrays and structures are other
types of containers that can store arrays that have different data types. So you can convert cell arrays
and structures to tables. You can also convert an array to a table where the table variables contain
columns of values from the array. To convert these kinds of variables, use the array2table,
cell2table, or struct2table functions.
For example, convert an array to a table by using array2table. Arrays do not have column names,
so the table has default variable names.
A = randi(3,3)
A = 3×3

a2t = array2table(A)
a2t=3×3 table

You can provide your own table variable names by using the "VariableNames" name-value
argument.
a2t = array2table(A,"VariableNames",["First","Second","Third"])
a2t=3×3 table
First
