How to display results in a table

Basically, I would like to display variables that depend on my inputs, in a table.

Here is a sample of my form :

<div class=”slidecontainer”>
<p>Fluid temperature (in ° C) :</p>
<input type=”range” min=”0″ max=”2000″ value=”200″ class=”slider” id=”myRange”>
<p>Temperature : <span id=”demo” </span></p>
</div>

<div id=”flow”>
<label for=”number”>Fluid flow</label>
<input type=”number” name=”flow”>
<select><p>select a unit:</p>
<option value=”Nm^3″>Nm^3</option>
<option value=”kg/s”>Kg/s</option>
</select>
</div>

<div id=”running time”>
<label for=”number”>Running time</label>
<input type=”number” name=”running time” min=”0″ max=”8784″>
<span>hours/year</span>
</div>

<div id=”fluid purity”>
<label for=”text”>Fluid purity</label>
<input type=”radio” name=”purity” value=”0″>0</input>
<input type=”radio” name=”purity” value=”1″>1</input>
<input type=”radio” name=”purity” value=”2″>2</input>
<input type=”radio” name=”purity” value=”3″>3</input>
<input type=”radio” name=”purity” value=”4″>4</input>
<input type=”radio” name=”purity” value=”5″>5</input>
</div>

For example :

Let T be the input fluid temperature
Let F be the input flow of the fluid
Let Rt be the input running time in hours
Let P be the input fluid purity (with 0 ≤ P ≤ 5)

I would like to set the following variables:

Y (Yield) = 17% if T≤300°C
Y = 0.1*T – 13 if 300° ≤ T ≤ 350°
Y =22% if T>350°

Then an intermediate variable T(out)=20*P + 120
and Δ(T) = T – T(out)

that helps calculate the Thermal Power TPw
TPw = 0,00042 * Δ(T) * F if the input unit chosen is Nm^3/h
TPw= 0,00042 * (1/1,3)* F * Δ(T) * 3,6 * 10-6 if kg/s unit chosen

That is just part of what I have to do but I have no idea of how to display those variables Y and TPw in a table after submiting my form 🙁
Do I have to use PHP or JS ?
