adjusting angularjs material design data table col

问题:

I'm using the old AngularJS Material Design Data Table and would like to know how to adjust the column width.

https://github.com/daniel-nagy/md-data-table

For instance if I wanted to change the 'fat' column in the demo to a fixed width of 40px how would I go about this?

Demo: http://codepen.io/anon/pen/BjvLVJ

There is a fixed padding which seems to be the main problem.

table.md-table.md-row-select td.md-cell:nth-child(n+3):nth-last-child(n+2), table.md-table.md-row-select th.md-column:nth-child(n+3):nth-last-child(n+2) {
    padding: 0 56px 0 0;
}

回答1:

You could use the following css class.

.width-override{
  width:40px !important;
  padding:0px !important;
}

You will need to add it to the th and td tags of the respective column like so.

<th md-column md-numeric md-order-by="fat.value" class="width-override"><span>Fat (g)</span></th>

<td md-cell class="width-override">{{dessert.fat.value | number: 2}}</td>

Please checkout the below example!

Note: The contents are of width 56px so the column is of that width, you might want to use the same, since we do not want to clip the contents inside the column.
