Partial Update #176

Closed gelinger777 closed 4 years ago

gelinger777 commented 4 years ago

I have a problem with re-rendering the whole component, as I have to update cell data each 1-2 seconds. The problem is that the numbers mostly change in several cells and not all table. Is that possible to partially update the data ?

Hi @gelinger777

Can you attach a demo where we can reproduce the issue? Please describe all the steps to do so.

Without it could be hard to fully understand your issue.

Hi @pnowak . I can't attach a demo. Imagine you have a initiated a normal table with 4 rows and 4 columns. Now you want to update only cell 2:3 (second column and 3rd row) or several columns. How to do it? Currently we update the data value and the whole table rerenders . Isn't it possible to update only 2-3 cells instead of the whole data?

We have a problem that the colwidth array is not working at all, and I have a clue that this could be the reason.

Unfortunately, it's impossible to render only one cell.

What do you mean colWidth array is not working at all? Doesn't render columns with appropriate width?

gelinger777 commented 4 years ago

no, it's not. probably because we use the free version (v6)

pnowak commented 4 years ago

I prepared a demo with a colWidths in Vue wrapper - https://codesandbox.io/s/col-width-n9pc2?file=/src/App.vue

It would be great if you could extend it to better reflect your issue.

Dear @pnowak I can't provide you full test case , as we have a very complicated case where data comes each second from a pusher subscribe, and data is so that float numbers length after dot change randomly, and because of that the table jumps left and right for 2-3 pixels. We have found other plugin which uses flexbox and divs , and we will abandon datatables. Thus I am closing the issue. Thank you for your time.
