DataTables fixed headers misaligned with columns in wide tables

Question

Problem  When using the sScrollX  sScrollXInner and or sScrollY to achieve a fixed header table with its inner content scrolling  the headers of the table go out of alignment with the rest of the body in Chrome and IE  Firefox  on the other hand  displays them perfectly   Using the version 1 9 4  as far as I can tell  this issue only occurs when there is a lot of data with fluctuating widths  and with words that are very long unwrappable combined in the same columns as small ones  Also  the table in question needs to be fairly wide   All these factors are demonstrated in this fiddle   Output  Chrome    IE    Firefox   Suggested Solutions  These solutions have been suggested before but have had no effect on my implementation  Owing to some of these suggestions  I setup a clean plain vanilla demo as I wanted to ensure that no other code was contributing to this effect    turn-off remove all my css setTimeout  function      oTable fnAdjustColumnSizing       10    calling oTable fnFilter   x  0   and oTable fnFilter     0   in that order  sScrollXInner    100   get rid of all widths   The only solution that I found to the misaligned headers was taking out sScrollX and sScrollY  but this can t be counted as a solution as you lose the fixed header inner content scrolling functionality  So sadly it s a temporary hack  not a fix   Note  To edit play with the latest fiddle   I have tried various combinations which can be observed in the revision history of the fiddle by using the link http   jsfiddle net pratik136 etL73  REV  where 1  lt    REV   lt   12  History  StackO This question has been asked before  jQuery Datatables Header Misaligned With Vertical Scrolling but the vital difference is that the OP of that question mentioned that they were able to fix the issue if all CSS was removed  which is untrue in my case  and I have tried a few permutations  thus thought the question worthy of a repost   External This issue has also been flagged on the DataTables forum     http   datatables net forums discussion 7395 sscrolly-and-sscrollx-broken p1 http   datatables net forums discussion 7778 vertical-scrolling-messes-up-column-header-alignment Item 1 http   datatables net forums discussion 3835 width-columns-problem-in-chrome-safari p1 My bug report  http   datatables net forums discussion 12491 datatables-header-alignment-issue-refresh Item 1   This issue has driven me nuts  Please contribute your thoughts

Add table-layout  fixed to your table s style  css or style attribute    The browser will stop applying its custom algorithm to solve size constraints   Search the web for infos about handling column widths in a fixed table layout  here are 2 simple SO questions   here and here   Obviously  the downside will be that your columns  width won t adapt to their content      Edit  My answer worked when I used the FixedHeader plugin  but a post on the datatable s forum seem to indicate that other problems arise when using the sScrollX option    bAutoWidth and sWidth ignored when sScrollX is set  v1 7 5   I ll try to find a way to go around this

I had this very same problem and seen a lot of complicated answers that never seemed to work  I did solve it by simply overriding the CSS  site css  on the following and it fixed it in Chrome  IE  and Firefox   table display td   padding  0px 5px       this is needed for IE and Firefox if using horizontal scroll   table      max-width  none      min-height  0       This overrides the CSS in datatable jui css

I know there has been an answer flagged already  but for someone with similar problems that the above does not work for  I m using it in conjunction with bootstrap theme   There is a line that can be altered in the dataTables fixedHeader js file  the default layout of the function looks as follows        matchWidths  function  from  to            var get   function  name                return   name  from                   map function                          return   this  width                       toArray                        var set   function  name  toWidths                  name  to  each function  i                      this  css                       width  toWidths i                       minWidth  toWidths i                                                          var thWidths   get  th            var tdWidths   get  td             set  th   thWidths           set  td   tdWidths            change the       return   this  width      to       return   this  outerWidth      outerWidth   is a function that is contained in jquery dimensions js if you are usingg a newer version of jquery  ie  jquery-3 1 1 js  what the above function does is it maps the th of the original table  then applies them to the  cloned  table fixed header   in my case they were always off by about 5px to 8px when misaligned  Most probably not the best fix out there but provides a solution to all other tables in the solution without having to specify it per table declaration  It has only been tested in Chrome so far  but it should provide an adjudicate solution on all browsers

EDIT  See the latest Fiddle with  fixed header       The Fiddle   One of the solutions is to implement scrolling yourself instead of letting DataTables plugin do it for you   I ve taken your example and commented out sScrollX option  When this option is not present DataTables plugin will simply put your table as is into a container div  This table will stretch out of the screen  therefore  to fix that we can put it into a div with required width and an overflow property set - this is exactly what the last jQuery statement does - it wraps existing table into a 300px wide div  You probably will not need to set the width on the wrapping div at all  300px in this example   I have it here so that clipping effect is easily visible  And be nice  don t forget to replace that inline style with a class      document  ready function     var stdTable1       standard-grid1   dataTable        iDisplayLength   -1       bPaginate   true       iCookieDuration   60       bStateSave   false       bAutoWidth   false        true      bScrollAutoCss   true       bProcessing   true       bRetrieve   true       bJQueryUI   true         sDom    t        sDom     lt  H CTrf gt t lt  F lip gt         aLengthMenu     25  50  100  -1    25  50  100   All            sScrollY    500px          sScrollX    100         sScrollXInner    110         fnInitComplete   function             this css  visibility    visible               var tableId    PeopleIndexTable       lt div style  width  300px  overflow  auto  gt  lt  div gt    append         tableId   insertAfter         tableId     wrapper div   first
