Slow execution uitable with many characters

Hello,

a has size for example (20,70000). If I insert a into uitable in GUI, than moving slide up/down or right/left is executing so slowly.

How can I executet ot faster?

Thank you?

That's an absurd size of data to try to display in a uitable -- section it down to something of manageable size. There's just no way it'll work responsively trying to display all the data at once (and no way to show more than 20 or so lines on the screen at a time, anyway).

Sorry,

a has size (20,1). But each line has aprox. 70 000 characters. I hope it is is better situation.

No, not really...same problem, you can't display more than 100 or so characters comfortably horizontally, either, and as you can see, the GUI just can't deal with the magnitude easily. You need a window into the file content for the display.

how can I do it ?....window...?

This is not a job for an uitable. It is simply not meaningful to display such a huge pile of data in a user interface. It is like asking for a diagram with millions of X-values. Neither a monitor, nor the human eye can copy with this amount of data. Therefore uitable is not designed to contain such a pile of data.

Therefore I suggest not to try to accelerate the display, but to choose another method for a visualization.

Try cropping the string to lets say... 50 chars, and add 'More...' string indicating that there's more data. who reads 70 000 chars anyway?
