kandi X-RAY | java-datatable Summary
Java DataTable is a lightweight, in-memory table structure written in Java. The implementation is entirely immutable. Modifying any part of the table, adding or removing columns, rows, or individual field values will create and return a new structure, leaving the old one completely untouched. This is quite efficient due to structural sharing.

QUESTION
I'm attempting to code my first website from scratch and I have found myself stuck on this problem for the last day. I am trying to center the logos for my mobile view. I have them placed correctly in my @media tag and they are displaying inside the grid however after countless tries I cannot get them to center inside of there grid columns. I do apologise if any of my code is messy.

QUESTION
I have a 3 x 3 grid with randomly placed obstacles in which there is a random starting point but no endpoint. The endpoint is created when there are no more cells to occupy. Movement can occur up, down, left or right.
How can I see all possible unique paths within the grid?
Example:
- Once a cell is used when looking for a path, it cannot be used again (1 becomes a 0).
- If there are no more neighbouring cells to move into the path has ended. Regardless of weather all the cells have been visited.
ANSWER
Answered 2022-Mar-28 at 09:24To get all the paths, you can use DFS or BFS but each path needs to have a unique visited set to keep track that you:
- do not go back to the same coordinate twice in a single path
- allow different paths to go on the same coordinate
I wrote a DFS implementation for a grid here and the solution will rely on this example.
SolutionTo do graph search one would need to define the states, which are the coordinates in this case, but for this problem we will keep track of two parameters, for convenience:
- The path taken will be documented via Crack code (right=0, down=1, left=2, up=3) which is a form of chain code
- the
visitedset for each path will de documented for the reasons noted above
The implementation in Python is as follows (in my case the top left matches coordinate (0,0) and lower right matches (n-1,n-1) for nXn grid)

I am trying to crease a grid of points corresponding to luminescence values in a 384-well plate experiment. I am drawing the plate as a .png file and overlaying the grid such that each point should sit in one well of the plate. Example code and data provided.
Is it possible to do this with ggplot2?
I am using the following code (example data provided):

Answered 2022-Feb-14 at 16:50By manually adjusting the position of the image with xmin/xmax & ymin/ymax, fixing the pitch of rows and columns with coord_fixed(clip = "off) and expanding the plot.margin in theme I was able to get something that seems like it will work.

QUESTION
ANSWER
Answered 2022-Feb-09 at 08:48If you don't mind using grid instead of flexbox, you can utilize the property justify-self to align the black box to the center with the help of position: absolute;. The absolute positioning here makes it so it's possible to align the black box toward the center without minding/affecting the other two boxes. See the snippet below:

I need the items in my listView to have a height so it the list exactly fits the screen. Here's my code given below. I tried setting the Height of rows in my grid to a custom value, but that would work well, fitting the screen in some devices, while there would be an empty space in other devices due to a different screen size.

I'm trying to make a grid of cards that hold an image and a title using Vuetify.
I have managed to make a grid with the help of a few examples and managed to make this (This is on breakpoint XL):
But the problem is that, if the screen goes smaller, the grid isn't much of a grid anymore, but rather looks like this (this is on breakpoint LG):
I'm using justification: space-between but if I use start this is the result:
My goal is to have a grid aligned with the v-divider above and also is justified in the start without the awkward gap in the second row in the LG breakpoint.

QUESTION
I'm currently using MUI Grid (but I'm open to alternate solutions) and I want two components side by side: the right most taking up 400px of width and the left component taking up the rest.
|<------------------------------- 100% of page ------------------------------->|
|<-------------------- Fill -------------------->| |<---------- 400px ----------->|
When page width is shrunk:
|<-------------------- 100% of page -------------------->|
|<--------- Fill --------->| |<---------- 400px ----------->|
My code is currently stretching the leftComponent to 100% of the page and pushing the rightComponent below it.
ANSWER
Answered 2021-Dec-22 at 22:11All you need to do is remove the number for your xs value. Doing this just tells the item to have a width of auto which will just fill the space
QUESTION
I have been trying to create a graph representing a square grid with 8 nodes. I have been using code given by Mathworks here:
...ANSWER
Answered 2021-Nov-10 at 15:37The graph G contains no coordinates for the nodes, so MATLAB basically has to "guess" where to put them (and does a remarkably good job). You can use the additional argument XData, YData (and ZData) to add coordinates to your nodes (see documentation), so in your case you might want to use e.g meshgrid:
QUESTION
Is it possible to use the dbc.Col and dbc.Row functions to set up the grid layout without using the bootstrap themes ?
When adding for example the codepen.io css stylesheet, even when specifying the rows and columns, it displays everything stacked vertically.
The reason for not using the dbc themes is that I would like to personalise an external stylesheet and use that. If there is no way around it, is it possible to override the dbc themes ? or modify them ?
...ANSWER
Answered 2021-Nov-03 at 18:37dbc.themes.BOOTSTRAP is just a link to a css stylesheet
