need to create tabular form which will update data from serial communication

You need to combine three parts:

0) Get the data from a serial communication. If you mean an RS232-port to read the data from, you can use the SerialPort class[^].

1) Your data model. Create a custom class with properties that reflect the data you want to represent. Decode what you got from 0) and feed the data into your model.
[Edit]
A simple data model class:

public class SingleDataPoint
{
    public decimal Temperature { get; set; }
    public decimal Voltage { get; set; }
    public decimal Current { get; set; }
}

This class has no logic in it. It's just for storing some values. Create an instance

SingleDataPoint oneSingleData = new SingleDataPoint();

and fill in the values

oneSingleData.Temperature = -273.15;
oneSingleData.Voltage = 42;
oneSingleData.Current = 0x0815;

If you need losts of those data points, keep them in a BindingList<SingleDataPoint>[^] for later easy binding to your UI.

2) Display the data. Bind your model to a DataGridView[^] for automatic updating.
