Software for Pre-CAD systems design


The SortedTable library creates unit-aware tables with sortable columns.

Here's a quick example table of the physical properties of common materials. Clicking the ↕ arrow sorts the table by that column while clicking on the [unit] allows the units of that column to be changed.

If your website is written in WordPress, see our WordPress demonstration website.

To add a sortableTable to your webpage, the first step is to load the library from Mechanomy as 'raw HTML':

<script defer src=""></script>

Then at the location you want the table to display, place this rather lengthy element, again as raw HTML:

<div class="SortedTable"
   caption="Mechanical Properties"
     units="lbm/in3:1, kg/m3:0.000036127; psi:1, Pa:6895, MPa:0.006895"
      data="Material,Specific Weight,Ultimate Tensile Strength,Ultimate Compressive Strength,Ultimate Shear Strength,Tensile Yield Strength,Shear Yield Strength,Modulus of Elasticity,Modulus of Rigidity,Coefficient of Thermal Expansion,Ductility
-,lbm/in3,psi,psi,psi,psi,psi,psi,psi,1e-6/F,pct elongation in 2 inch
Structural Steel (ASTM A36),0.284,58e3,-,-,36e3,21e3,2.90E+07,11.2,6.50E-06,21
Stainless AISI 302 Annealed,0.286,95e3,-,-,38e3,22e3,28e6,10.8e6,9.60E-06,50

Aluminum 6061-T6,0.098,38e3,-,24e3,35e3,20e3,10.1e6,3.7e6,1.31E-05,17
Douglas Fir,0.017,15e3,7.2e3,1.1e3,-,-,1.90E+06,1.00E+05,-,-

Within the sortedTable element:

  • class="sortedTable" identifies this <div> as the location for a sortedTable
  • id="materialPropertiesUnits" uniquely identifies the table on the page; if multiple tables are on the same page they need to have different ids
  • caption="Material Properties" this is the optional table title
  • units="lbm/in3:1, kg/m3:0.000036127; psi:1, Pa:6895, MPa:0.006895" specifies two unit systems that may be used in table columns, following the same format as in the UnitConverter, with unit systems separated by semicolons
  • data ="Material,..." this provides the data for the table with headers on the first line followed by an optional row of default unit, and then the table body. Three formats may be used: tab-newline, comma-newline, and comma-semicolon; the example above delineates columns with commas and rows by newline. For simplicity, the entered data must be square, which is to say that each row must have the same number of entries.

By default the sortedTable will inherit your page's default table appearance, but this can be overidden by adding a <style> tag as these examples show:


  • NEMA Motor dimensions
     #nemaSizes table{ border-collapse: collapse; text-align:center; color: black; }
     #nemaSizes th[scope='col'] { font-family:inherit; color: #444444; background-color:#dfecff;/*the header*/ }
     #nemaSizes tr:nth-child(odd){ background-color:inherit; }
     #nemaSizes tr:nth-child(even){ background-color:#f5f5f5; }
<div class="sortedTable" id="nemaSizes" caption="NEMA Motor Sizes"
units="mm:1, cm:0.1, in:0.03937; N*mm:1, N-m:0.001, ozf*in:0.1416119, lbf*in:0.0088508, lbf*ft:0.7376"
data="Reference, Motor Size, Bolt Hole Square, Motor Shaft Diameter, Motor Shaft Length, Average Torque

NEMA 23, 2.3, 1.854, 0.250, 0.810, 40"></div>
  • Drill and Tap sizes
     #drillTapChart table{ border: 2px red solid; text-align:center; color: black; font-size:small}
     #drillTapChart th[scope='col'] { font-family:inherit; color: #444444; background-color:#eeaaaa;/*header*/ }
     #drillTapChart tr:nth-child(odd){ background-color:inherit; }
     #drillTapChart tr:nth-child(even){ background-color:#eee; }
     #drillTapChart td {border: 1px solid black;}
<div class="sortedTable" id="drillTapChart" caption="Drill and Tap Sizes" precision="3" 
units="in:1, mm:25.4"
data="screw size number,screw size decimal,number of threads per inch, tap drill number,tap drill size,close fit drill number,close fit drill size,free fit drill number,free fit drill size;
