Make a surrounding div-tag  and set for it display  grid in its style attribute    lt div style  display  grid               text-align  center              background-color  antiquewhite   gt     lt table gt       lt tr gt         lt th gt Month lt  th gt         lt th gt Savings lt  th gt       lt  tr gt       lt tr gt         lt td gt January lt  td gt         lt td gt  100 lt  td gt       lt  tr gt       lt tr gt         lt td gt February lt  td gt         lt td gt  80 lt  td gt       lt  tr gt     lt  table gt   lt  div gt    The text-align property is set only to show  that the text in the regular table cells are affected by it  even though it is set on the surrounding div  The same with the background-color but it is hard to say which element actually holds the background-color

If you want all your columns a fixed size  you could use CSS   td PerformanceCell       width  100px      Or better  use th TableHeader  I didn t notice that the first time around

I m also open to suggestion on how to tidy this up  if there are any   -    Well  you could not use the span element  for semantic reasons  And you don t have to define the class PerformanceCell  The cells and rows can be accessed by using PerformanceTable tr    and PerformanceTable tr     respectively   For the spacing part  I have got the same problem several times  I shamefully admit I avoided the problem  so I am very curious to any answers too

You could always just set the width of each td to 100  N columns    lt td width  x   gt  lt  td gt

In your CSS file    TableHeader   width  100px      This will set all of the td tags below each header to 100px  You can also add a width definition  in the markup  to each individual th tag  but the above solution would be easier

I was designing a html email and had a similar problem. But having every cell with the fixed width is not what I want. I'd like to have the equal spacing between the contents of the columns, like the following

|---something---|---a very long thing---|---short---|

After a lot of trial and error, I came up with the following

<style>
    .content {padding: 0 20px;}
</style>

table width="400"
    tr
        td
            a.content something
        td 
            a.content a very long thing
        td 
            a.content short

Issues of concern:

Outlook 2007/2010/2013 don't support padding. Having the width of the table set will allow the widths of the columns to automatically set. This way, though the contents will not have equal spacing. They at least have some spacing between them.
Automatic width setting for table columns will not give equal spacing between the contents The padding added for the contents will force the equal spacing.

You can use CSS  One way is to set table-layout to fixed  which stops the table and it s children from sizing according to their content  You can then set a fixed width on the relevant td elements  This should do the trick   table PerformanceTable       table-layout  fixed      width  500px        table PerformanceTable td PerformanceCell           width  75px          Suggestions for for tidying up  You don t need the cellpadding or cellspacing attributes  or the TableRow and TableHeader classes  You can cover those off in CSS   table          cellspacing        border-collapse  collapse      border-spacing  0    th          This covers the th elements      tr          This covers the tr elements      th  td          cellpadding        padding  0      You should use a heading  e g   lt h2 gt   instead of  lt span class  Emphasis  gt  and a  lt p gt  or a table  lt caption gt  instead of the Source  lt span gt   You wouldn t need the  lt br gt  elements either  because you d be using proper block level elements

Take the width of the table and divide it by the number of cell ().

PerformanceTable {width:500px;}    
PerformanceTable.td {width:100px;}

If the table dynamically widens or shrinks you could dynamically increase the cell size with a little javascript.
