Rotating text within a HTML table header and resizing width of the column

Hello, firstly thanks to the community for so much existing content to help with this but I haven’t been able to get to the bottom of my issue. I am relatively inexperienced with html/css so any feedback it appreciated.

My workflow for this problem looks like this:

importing data as a dataframe
converting dataframe using to_html() with a class called ‘myfavourite_table’
embedding that table in an existing html document and then using WeasyPrint to export it to a PDF.

The header titles for this table are substantially longer than the necessary width of the columns for the remaining data, so I have been working on rotating the text and resizing the columns appropriately. I have had two major issues with the html (this is prior to WeasyPrint pdf prep):

The column widths will not reduce once the text is rotated
The text keeps wrapping

.myfavourite_table {
  font-size: 9pt;
  font-family: Arial;
  border-collapse: collapse;
  border: 1px solid silver;
  border-spacing: 0px 10px;
  text-align: center;
  vertical-align: middle;
}


.myfavourite_table th:not(:nth-child(12)) {
  transform: rotate(-90deg) translate(0, 0px);
  writing-mode: vertical-rl;
  padding: 0;
  margin: 0;
  height: 150px;
  white-space: no-wrap;
  font-size: 8pt;

}

.myfavourite_table th:nth-child(12),
td:nth-child(12) {
  text-align: left;
}

.myfavourite_table td {
  padding-top: 0.8em;
  padding-bottom: 0.8em;
}

.myfavourite_table tr:nth-child(even) {
  background: #E0E0E0;
}

<table border="1" class="dataframe myfavourite_table">
  <thead>
    <tr style="text-align: right;">

I have formatted a target output in excel as shown below. For reference, I am not expecting this to be presented as a HTML (yet) but mainly for feeding into WeasyPrint.

Any help is greatly appreciated 🙂

You may use transform:scale(-1) to reset other way your rotated text ( FF has sideways-xx that could be used).

padding and line-height can help too to tune text-position in the cell.

Here a possible example to play with:

.myfavourite_table {
  font-size: 9pt;
  font-family: Arial;
  border-collapse: collapse;
  border: 1px solid silver;
  border-spacing: 0px 10px;
  text-align: center;
  vertical-align: middle;
}


.myfavourite_table th:not(:nth-child(12)) {
  writing-mode: vertical-rl;
  padding: 0;
  margin: 0;
  white-space: no-wrap;
  font-size: 8pt;
  /* added */
  text-align: center;
  transform:scale(-1);
  padding:0.25em 1em;
  line-height:0.5;  
  vertical-align: top;

}

.myfavourite_table th:nth-child(12) {
  text-align: center;
}
.myfavourite_table td:nth-child(12) {
  text-align: left;
}

.myfavourite_table td {
  padding-top: 0.8em;
  padding-bottom: 0.8em;
}

.myfavourite_table tr:nth-child(even) {
  background: #E0E0E0;
}

<table border="1" class="dataframe myfavourite_table">

for FF , you could use : https://developer.mozilla.org/en-US/docs/Web/CSS/writing-mode#sideways-rl

.myfavourite_table th:not(:nth-child(12)) {
  writing-mode: sideways-lr;/* modified */
  padding: 0;
  margin: 0;
  white-space: no-wrap;
  font-size: 8pt;
  /* added */
  text-align: center;
  padding:0.25em 1em;
  line-height:0.5;  
}

No idea then how that will be converted within your PDF. It would be nice to let us know 😉

It appears that the CSS writing-mode property has a value sideways-lr which should arrange the text as per your target output. Unfortunately, browser support for that value is limited to Firefox at present.

I’d suggest just using vertical-rl for now. It’s not as neat as sideways-lr would be, but it’s usable.

.myfavourite_table {
  font-size: 9pt;
  font-family: Arial;
  border-collapse: collapse;
  border: 1px solid silver;
  border-spacing: 0px 10px;
  text-align: center;
  vertical-align: middle;
}


.myfavourite_table th:not(:nth-child(12)) {
  writing-mode: vertical-rl;
  font-size: 8pt;
}

.myfavourite_table th:nth-child(12),
td:nth-child(12) {
  text-align: left;
  vertical-align: bottom;
}

.myfavourite_table td {
  padding-top: 0.8em;
  padding-bottom: 0.8em;
}

.myfavourite_table tr:nth-child(even) {
  background: #E0E0E0;
}
