Final Answer:
Declare a 2D array called table with 3 columns and 4 rows of type integer.
Step-by-step explanation:
To declare a 2D array called "table" with 3 columns and 4 rows of type integer in a programming language like C++, you would use the following syntax:
```cpp
int table[4][3];
```
In this declaration, "table" is the name of the array, and it is defined with 4 rows and 3 columns. The order of dimensions is specified inside the square brackets, with the number of rows coming first and the number of columns second. In a 2D array, the first index represents the row, and the second index represents the column. In this example, "table" can hold 4 rows and 3 columns of integer values.
It's important to note that array indices in most programming languages typically start from 0. Therefore, the valid indices for the rows would be 0, 1, 2, and 3, and for the columns, the indices would be 0, 1, and 2. This declaration allocates memory for the array but does not initialize the values within the array. Initialization would be done separately based on the specific requirements of the program.
