css html-table spacing

I think I have it in this fiddle and I updated yours:

tbody:before {
    content: "-";
    display: block;
    line-height: 1em;
    color: transparent;
}

EDIT better & simpler:

tbody:before {
    content:"@";
    display:block;
    line-height:10px;
    text-indent:-99999px;
}

This way text is really invisible

Moreover you can use Zero-Width Non-Joiner to minimize sinsedrix CSS:

tbody:before {line-height:1em; content:"\200C"; display:block;}

Solution 3

This will give you some white space between the header and table content

thead tr {
  border-bottom: 10px solid white;
}

Although setting the border colour is a bit of a cheat method, it will work fine.

Form investigation, you can't set box-shadow to a table row, but you can to table cells:

th {
  box-shadow: 5px 5px 5px 0px #000000 ;
}

(I'm not sure how you want the shadow to look like, so just adjust the above.)

Solution 4

This worked for me on Chrome (for other browsers I don't know).

.theTargethead::after
{
    content: "";
    display: block;
    height: 1.5em;
    width: 100%;
    background: white;
}

Such css code creates an empty white space between the thead and the tbody of the table. If I set the background to transparent, the first column of the above tr > th elements shows its own color (green in my case) making about the first 1 cm of the ::after element green too.

Also using the "-" sign in the row content : "-"; instead of the empty string "" can create problems when exporting the printed pages to file, i.e. pdf. Of course this is parser/exporter dependent. Such exported file opened with a pdf editor (for ex.: Ms word, Ms Excel, OpenOffice, LibreOffice, Adobe Acrobat Pro) could still contain the minus sign. The empty string doesn't have the same issue. No problems in both cases if the printed html table is exported as image: nothing is rendered.

I didn't notice any issue even using

content : "\200C";

Solution 5

So box-shadow doesn't work well on the tr element... but it does work on a pseudo content element; sinsedrix put me on the right track and this is what I ended up with:

table {
    position: relative;
}

td,th {padding: .5em 1em;}

tr.even td { background-color: yellow; }
tr.odd td  { background-color: orange; }

thead th:first-child:before {
    content: "-";

    display: block;
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    z-index: -1;

    box-shadow: 0 1px 10px #000000;
    padding: .75em 0;

    background-color: #ccc;
    color: #ccc;
}

thead th {
    padding-bottom: 2em;
}

I have a simple html table like this:

<table>
  <thead>
    <tr><th>Column 1</th><th>Column 2</th></tr>
  </thead>
  <tbody>
    <tr class="odd first-row"><td>Value 1</td><td>Value 2</td></tr>
    <tr class="even"><td>Value 3</td><td>Value 4</td></tr>
    <tr class="odd"><td>Value 5</td><td>Value 6</td></tr>
    <tr class="even last-row"><td>Value 7</td><td>Value 8</td></tr>
  </tbody>
</table>

And I would like to style it the following way:

header row with a box-shadow
whitespace between the header row and the first body row

Box Shadow on Header + Spacing to Body

I have tried different things:

table {
    /* collapsed, because the bottom shadow on thead tr is hidden otherwise */
    border-collapse: collapse;
}
/* Shadow on the header row*/
thead tr   { box-shadow: 0 1px 10px #000000; }
/* Background colors defined on table cells */
th         { background-color: #ccc; }
tr.even td { background-color: yellow; }
tr.odd td  { background-color: orange; }

/* I would like spacing between thead tr and tr.first-row */

tr.first-row {
    /* This doesn't work because of border-collapse */
    /*border-top: 2em solid white;*/
}

tr.first-row td {
    /* This doesn't work because of border-collapse */
    /*border-top: 2em solid white;*/
    /* This doesn't work because of the td background-color */
    /*padding-top: 2em;*/
    /* Margin is not a valid property on table cells */
    /*margin-top: 2em;*/
}
